Stop in for a cup of coffee

I have tried the citrus stuff, barley does the job after a day covered with plastic.
Citristrip? Not surprised it doesn't work for that.
Its pretty good for taking the last coats of varnish or paint off of wood. Much slower, but when working a large area like a floor that's actually an advantage. Pick it up using woodshavings a few hours later or the next morning. Then wipe down.

When I run into some crusted up grease, and the green or purple doesn't work, sometimes fuel works. Failing that, engine foam or uncoat remover. I don't know what's in that undercoat remover but it really cuts through when other stuff won't. upload_2019-3-27_12-48-6.png
