Very Poor Results From Heng's Roof Coating

I made a similar mistake with mineral spirits. I was trying to clean every last bit of old caulk off of a small area and the mineral spirits rippled up the rubber membrane. I waited about a week and the ripples flattened out and the membrane look normal. The local trailer repair shop near me told me not to use Hengs and a local commercial roofing supplier told me to use Henry’s. I’ve done two RVs with Henry’s and I pressure washed to remove anything that would possibly break loose and then I used a Scotch-Brite pad and TSP solution to clean the membrane. I used Henry 587 on a previous RV when I lived in the Phoenix area and it still looked awesome after five years of outside storage, when I sold it. I used Henry 787 on this fiver two and a half years ago and it still looks like new, too. If I ever do another one I will use the Henry 887 which is 100% silicon and it is recommended for RVs. I’ve had zero problems with the cheaper Henry products though. Craig
