super tacky

Really good stuff this Bel Ray foam filter spray...super tacky and pretty good at repelling water...now don't go submerging your bike in water like I had … the unfortunate incident left my bike sitting in water ,just below tank for a few minutes . I was amazed when I went to pull filter off to begin the dreaded upside down clearing of water, that the filter had stopped the flow of water into the intake!. I do use Bel Ray waterproof grease also, to seal the filter to the air box as well. All good reasons to keep using their stuff!
