My canvas mooring cover (snap in) looks almost new, but water seeps through the canvas and gets into my boat. It keeps MOST water out, but i don't want any in. Will formula 303 take care of this? Any other suggestions?
Hmmm, interesting. I'll look into it. I have heard 303 works good, although i may spring for some stuff with PTEF in it for UV protection. BassPro makes a waterproofing spray with PTEF.
