"Honey have you seen my knee-pad?" "Um, well here's the thing. I caught the dog chewing on it, and it was a mess. Why don't you buy yourself a new knee-saver?" I used a kitchen sponge I found under the kitchen sink that I am pretty sure my wife didn't need, and it worked much better than sandpaper alone.

I think I have settled on about 50/50 for mineral spirits and paint mixture. I know now I had it way too thick which is what caused some earlier issues(see picture).
