Body fillers in general seem to have gotten a bad rap over the years, which is likely due to misuse by do-it-yourselfers and hack bodymen who overdo it, but actually even the high-end body shops use body filler to finish their work. The rule of thumb is you don’t fill anything deeper than a quarter of an inch with standard filler such as Bondo, but there are actually some other types of fillers that are safer to use to repair other damage such as rust holes. Kitty Hair or other fiberglass-impregnated fillers are waterproof, rustproof, and much sturdier than standard fillers when they cure. Because the strands basically lock together when the mixture dries, it’s ideal for fixes where you need to reshape or sculpt an area.
