It would be nice if you told us what you are doing and what you want to powder coat and why you need filler. Normally things that get powder coated are solid metal pieces and frames of trucks, not sheet metal with dents? Body parts get painted not powder coated. If it's a steel bracket or other with too many holes or gouges: Weld and grind baby! Remember, as a new guy, to explain what you are doing, and to what.
