3M Paint & Rust Stripper, Large, 4 inch, Use on Wood, Metal, Plastic, Fiberglass, 1 Disc, 7772ES

I use these 4-inch 3M Paint %26 Rust Stripper discs for automotive paint stripping, and they save me hours of tedious hand-sanding or dealing with messy chemical strippers. I have tested it across multiple surfaces, including both metal and wood, and it performed very well on each. It removes rust, scaling, and old paint quickly without digging into or gouging the underlying material, leaving a nicely prepped surface ready for priming or painting. I like that they fit a standard drill and hold up well under pressure. Like all 3M products, it is high quality and maintains its abrasive structure even when tackling heavy paint buildup or rust. The 4-inch size offers great surface coverage while still being nimble enough to get into tighter spots. Final Verdict: If you have an automotive, restoration, or DIY project involving paint and rust removal, this is worth every penny. I highly recommend it.

These are the best, have used other brands and they dont work as well. great price and does the job.
