The roof of my houseboat is covered with decades old gelcoat
which is cracked and leaking. I would like to cover it with elastomeric and I've seen roofs where people have done that. One of the roofs looks fine like the elastomeric did great. On another one there are spots where the rubber is pealing off. I had thought that elastomeric and rubber roof stuff were the same thing and elastomeric is just a brand name, but in another thread I saw where a person specifically said that elastomeric is good but that rubber roof stuff will peal off. What's the difference and what to look for? Is it true that elastomeric works well, but the rubber stuff does not?
Thanks for any help with this!
