Query: This Stuff Really Works!

I bought this stripping gel to strip the poly and paint from a guitar body. Of course it wasn't designed for that, but the guitar body was made of wood, so... I used a brush and painted one side of the guitar body with the stripper, then waited about an hour. One thing I noticed immediately. You need to wait until the gel completely dries and forms a sort of "crust" on the finish before using a putty knife or other instrument to scrape it all off. If you try scraping while the gel is still wet, it won't work well at all. At least it didn't for me. Once dry though, you scrape off stripper, finish, and paint...all in one motion! This stuff worked to perfection, and it really doesn't take a huge amount spread on the wood to get the effect you need.I still have a ton of it left in the bottle, and will be using it for my next wood project for sure.
