With mineral spirits I have found that I only have to wait a few days before rubbing out. With water it was weeks ( or months )! On this last job I used naptha. Even better because it evaporates quickly and has no oily residue. I also think that, for this reason, it does not interfere with the friction cutting of the abrasive, while providing a nice thin medium to flush out the sand-off. Worked very quickly! Thump Interesting idea I haven't had any problems with the soapy water gumming up since I started using more soap. We use an in line air-wet sander from Detroit pneumatic, I think its called, for all our flattening & rub out prep. It's a real time & labor saver. It holds two 4 by 8 inch pieces of sandpaper. I find that I can rub out easily after about 10 days. Longer is better but not really necessary in the dry calif.heat. I like the idea of Mineral spirits or naptha in case I need to push something out quicker. Thanks for the tip Dale ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
