Now, let’s begin with pictures of the two damaged wheels:
The above pictures should give you a good idea of the extent of damage done. Pretty much the entire face of each wheel was affected.
After doing some research on the internet, I found a “matching” silver paint for the silver OEM BBS wheels. Wurth makes a silver lacquer that supposedly matches the OEM BBS’. They also make a clear lacquer, which is the accompanying clearcoat product. Therefore, I decided to give it a chance and ordered both products. ( Wurth Products and Other Porsche® Parts and Porsche® Accessories by Performance Products)
Here is a list of materials that you will need for this project:
- Wurth Silver Lacquer Paint – 1 can (I used 1 can for 2 wheels)
- DupliColor High Performance Wheel Coating (clear coat) – 1 can (I used 1 can for 2 wheels)
- DupliColor Sandable Primer – 1.5-2 cans (I used 1.5 cans for this, but I messed up on 1 primer coat)
- Blue Painters Tape
- Bondo Spot Putty
- 220 Grit Sandpaper
- 400 Grit Sandpaper
- 1500 Grit Sandpaper
- AutoPrep Automotive Paintwork Cleaner (removes wax, etc, really strong stuff)
It should be noted that for pretty much all of the following steps, I was wearing a small white respirator, to protect me from any harmful fumes. (small mouth covering face mask)
Step 1 – Clean the wheel
Start out by thoroughly cleaning the wheel. I used SimpleGreen for this task, with the added help of a garden hose to thoroughly hose everything off. After getting the wheels squeaky clean, I also used the AutoPrep paintwork cleanser and sprayed it on. After spraying, let it sit for about 1 minute before wiping off. (warning: this stuff is REALLY strong, do this outside and be careful of fumes)
Step 2 – Light Sanding
After cleaning, lightly sand down the wheel. You may opt to tape off the tire sidewall portion of the wheel at this time, although I did not do this until later. Mainly focus on the areas which are going to be repaired. For this task, I used 220 grit sandpaper.
Eventually you’ll begin to see metal, which will actually have a shine to it in certain cases. Also be sure to sand/rough-up any scuffed areas, as this will be important for the Bondo to properly adhere to the wheel.
Step 3 – Bondo
After fully sanding down the wheel, begin to apply the Bondo spot putty. This was my first time ever working with Bondo, and therefore I was quite generous with the product. Applying too much Bondo to an area has no ill-effects; it’s just more material to sand off later on. Please note that you MUST wear a respirator during this step, as many of you know Bondo is really strong stuff, and the fumes/odor can be harmful.
The spot putty consists of two elements. The white putty, and the red hardening cream. When mixed, the bondo has roughly 5 minutes until it hardens. According to the directions, one must mix first, then apply the product to the application. (in this case, the wheel) Although I didn’t feel like getting too messy with things, so I simply goo-ed on the white bondo all over the wheel. Following this, I applied the red hardening cream ontop of the white goo, and mixed it all together while wearing rubber latex gloves. (and while both products were already on the wheel)
A picture best describes this:
Step 4 – Bondo & wheel sanding
Let the wheel sit for some time, allowing the spot putty to full-dry. I believe the directions stated the putty could be sanded within 30 minutes of application, but I didn’t want to risk it. Therefore, I simply let it dry overnight. (not necessary, an hour or so should do)
After the putty has fully dried, take out your 220 and 400 grit sandpaper, and begin to sand the putty down. Again, be careful and wear a respirator, as sanding creates lots and lots of small particles. (bondo flavor! ) I started out sanding down the bondo’d areas with 220 grit, following up by 400 grit. You should also sand down the rest of the wheel at this time, to fully even things out.
Sand the puttied areas down until they are flush/smooth with the rest of the wheel surface. Once sanding is complete, the surface of your wheel should be completely smooth. If not, add more putty if desired and repeat. I managed to get by on the first try, and most likely you will be able to as well.
Once the wheel attains a smooth surface, any pink areas left should represent a scratch, scuff, or gouge that was filled in by the spot putty.

Step 5 – More wheel cleaning
After sanding, be sure to clean the wheel again thoroughly, making sure no sand dust is left behind. Most likely, there will be lots of dust left behind, so I sprayed some AutoPrep paintwork cleaner. Again, this stuff is very strong, and did a great job of cleaning the dust up. I also used my shop vac, which allowed me to suck up the loose dust prior to cleaning the wheel.
Step 6- Prep work
Prep work! Now that the wheel is squeaky clean, your going to want to tape off any areas that you don’t want to get paint onto. That includes your beautiful STi! During my project, I actually had my wheels on an old red wagon, so I could wheel them around, and also did all paint spraying outside. (and closed the garage door behind me, preventing any paint from hitting my car)
I recommend taping off the sidewall of your tire, the silver wheel hole bearings, and the black valve stem & cap. I used simple blue painters tape, which worked well and held up great throughout the painting process.
Cut out some newspaper, and tape it to the inside of your wheel, preventing any paint from hitting this area. I also put painters tape onto the backs of the spokes.
During spraying, it’s also VERY handy to have a stack of note cards. You can prop these up between the tire sidewall and the lip of the wheel. These also work great in protecting the tire from getting paint on it.

Step 7 – Primer
After fully sanding down the wheel, your ready for primer! I purchased some “Duplicolor Sandable Primer” for this task. This product is available in different colors, so don’t get confused! All colors are the same formula, and it will be hidden underneath your paint anyways. I opted for the gray color.
Apply 3-4 coats of primer. I sprayed very light coats, and allowed about 15 minutes in between the first 2 coats. After applying coat #2, I allowed the wheel to dry for a few hours, making sure it was fully cured. After fully drying, I was able to see the finish it left, and then applied coats 3 & 4, being sure to cover any areas that I missed. It should be noted: It’s better to apply 3-4 light coats, than to apply 1-2 heavy coats, to prevent running.
If you do get some running, no need to worry, simply be sure to let the primer fully dry, and then sand the affected area, followed by respraying.
After the primer has fully dried, lightly sand it with 400 grit sandpaper. Once sanding is complete, suck up the remaining dust with a shop vac. DO NOT USE AUTOPREP CLEANER ON THE WHEEL AT THIS POINT! AutoPrep cleaner is so strong it will strip the primer right off. If you have remaining dust left over, use a softer/less harsh cleaner. I opted for a light mix of SimpleGreen.

Step 8 – Time for Paint!
After allowing the primer to fully dry, it’s time for paint. Again, I applied 3-4 coats, and these were very light coats. The Wurth silver lacquer has a very metallic look to it, and the shiny metal flakes will fly everywhere, so be extra careful to protect anything in the surrounding area that you don’t want paint on.
Apply 3-4 coats of Wurth silver lacquer. I applied the first two coats, waiting 15 min in between coats. After the 2nd coat, I let the paint fully dry for 1 hour, then applied 2 more coats, again waiting 15 minutes in between.
Step 9 – Clearcoat
Now I had originally ordered the Wurth clear lacquer as well, so like anyone else would do, I applied it after the paint was done drying. Although unfortunately, it did not deliver the shine that I wanted. Therefore, after doing some reading on the int4rw3bz, I set off to Advance Auto Parts, and picked up some DupliColor High Performance Wheel Coating. (the clear color!!) The product ended up working great, and now technically one of my wheels has two types of clear coat applied to it.
After the paint has fully dried, apply 3-4 coats of clear coat. Again, follow the rule of 15 minutes in between coats. (and allow 1 hour drying time after the 2nd coat) Also, I highly suggest allowing the 1 hour drying time after coat #2, to thoroughly check for any missed areas, as it’s hard to see where the clear coat hasn’t been applied to. (because it’s clear )
After the last coat of clear coat, be sure to let the wheel fully dry. This step is very important, as it’s sensitive to the final finish of your wheel(s). Also, be sure not to use any types of cleaner on the wheel for a few days, to let the recently applied clear coat fully de-gas. (polish should be ok, but hold off on the wax if you can)
Step 10 – Admire the finished product
That’s it! Give yourself a pat on the back. I never thought that I would be able to complete a project such as this, but I just did a lot of reading, and pretty much said to myself it’s worth a shot. I wanted to have my wheels repaired anyways, so I figured if they came out undesirable, I would just have a bodyshop re-do them. Though the bodyshop may do great work, they also charge $150 per wheel.
So there you have it folks: Your BBS wheels are now back in great shape, and all of this was done for less than $50!
I apologize for the large size of the pictures, but when I was initially doing research on how to fix my wheels, I wanted large detailed pictures. Therefore, I’ve given the IWSTI community just that in return!

Here are some finished shots of my BBS wheels. Both repaired wheels are on the right side of my car.
This part of the lip used to be scuffed like crazy, now it looks brand new! :
