I have been doing body work all wrong.

Drywall seam tape, spackle, covered w/ Imron!! Rolled-up cardboard shoved into a hole, cut flush, then a blob of Tiger Hair pushed in...skimmed then covered with wax paper. When it heats up & turns solid the paper peels right off. Tin flashing & Liquid Nails. Wood screws & heavy plastic sheet left-over from whatever. Screws & washers holding shingles/roll-roofing. Just off the top of state insp.-only, or worse, actual body shop **** I've seen in PA.
