removing undercoating.

we all know this job sucks badly. there are many ways to do this job, all of em suck. however theres ways to make em suck less. i found that using WD-40 on the undercoating and letting it sit for awhile loosens it up, but requires multiple applications of WD-40 over a weeks time and time to let it soak in to get it to soak thru.

i found something that works sooo much better and quicker. DOT 3 brake fluid. yes the job still sucks, but this stuff when brushed on starts soaking right in almost immediately, let it sit for a day or 2, and the undercoat will almost fall off in chunks with a metal scraper against it. i use a scraper that holds razor blades in it.

you can remove the excess with a wire wheel on an angle grinder, and follow it up with with laquor thinner and some clean cloths.

hope this helps
