I used both the Flex Seal tape and liquid spray on my RV and it leaked and caused $20,000 worth of damage and I put a complaint against the company and they denied it after I sent both pictures and estimate for the damage. I have informed all family friends and co workers to spread the word and not buy as they don't stand behind their product. They were willing to pay me for the product but give no money towards the damage. DO NOT BUY as it doesn't work and we followed the directions to the letter. Poor customer service and false advertisement! BEWARE of this product!
Bottom Line: No, I would not recommend this to a friend
