My camper roof was warped because I stored it in a lot over the winter and spring so it has a lot of huge cracks that go all the way through the roof down to the wood. Could this technique still be used or would I have to replace the roof? It's the same material roof as the camper you worked on.
Potentially a tiny bit, but I can say because I converted this popup to a enclosed trailer, when we removed it, the foam was perfectly fine. I dont think enough acetone can get to the foam to do any real damage.
