I'm looking to get another Multi B board, as fast as possible. I'd prefer it to be already waterproofed/e6000'd. I've tried several times on my own board and just havent been happy with the results. Trying to peel off the old thick multiple layers of e6000, I think I messed it up. I havent tried it yet, but I figured I'd put out the feeler in case it doesnt work anymore. If it's at all possible to get it shipped out Monday and delivered before the 3rd, that would be awesome. I'm willing to pay for the extra shipping speed as well.
Try MG Electronics Conformal coating. Usually takes 2 or 3 coats. Clear and thin. I get it on Amazon.
