I would like to powder coat my disc wheels, however they have a lot of pits in them and I think that will really show with powder coating. I was told that bondo will not work with powder coating because it can not tolerate the heat of the powder coating process. Is there anything a powder coating firm can do to fill in those pits before the final coat? Thank you.
Dave,
I was told by a powder coating business not use bonds. They told me to use JB weld.
Dave,
Sand/bead blast the parts and use "Hi-Temp Lab Metal". I get it from Fastenal. It's pricey, but, you mix it up well and apply it like you would do bondo. After about 30 min you can sand etc., then take to the powder coater the next day and tell them what you used. Instructions say "cure", but, the powder coating oven will take care of that. If your powder coater didn't know of this stuff, maybe you should look for another one! Good luck, and contact me if you have any questions.
