I repaired and painted mine. I learned a few things.
- U-tube video suggested using a clay like epoxy product that has the hardener in the center. You knead the clay until all is mixed. In the end, it did not stick completely to all the crack surfaces. I would not use this product. When I redo it next I plan to use JB Weld to fill the cracks. Note: I did use a Dremel to cut out the cracks. This made the cracks wide enough to fill and the edges were clean.
- If you have the ridges on your wheel, I put 1/4" tape over the ridges to keep the extra epoxy from getting into ridges. When you are closer to being ready to paint, I would fill the cracks that tun through the ridges.
- Sanding is the tricky part. You have to sand off the extra epoxy without removing the existing plastic around the epoxy or creating a flat spots. Also the 1/4" tape helps to keep the sand paper away from the ridges.
- Paint process is important. I used a primer and sealer and then epoxy from VHT. It worked well but I did scratch the paint when i got in and out of the car so i will do it again, I am going to try the process noted below and add a few coats of the 2K clear coat to add additional paint protection.
