Filler before Powdercoat
-
I need to know if anyone has a suggestion for a powdercoat filler to cover surface imperfections in steel. Bondo [linked by editor to product info at Amazon] won't do as it emits gasses that won't allow good adhesion.

I have found a product that works well for me. Although maybe not too efficient for large scale operation, when we have a few parts that have pits, we use a Metal Repair Stik made by Permatex [Permatex Multi-metal Epoxy Stick [linked by editor to product info at Amazon]]. It's a small roll of 2 components that you pinch off, roll into a well mixed ball, and smooth onto the imperfection. While it is still soft, we can smooth it to a nice finish with just a good rub of the finger. Good luck.
