I believe that the entire roof may have pinholes so I'm coating the whole thing.
It's a 1994 Four Winds 5000 which is 29 feet. I have ripped out most of the wood and foam in the cab-over and I plan on rebuilding that when I can. First I'm just trying to seal it and stop leaks. Later I'll reinstall the foam and put in new wood framing as needed. It has some aluminum framing.
I plan on cleaning the aluminum roof with TSP (tri-sodium phosphate) before I apply the elasomeric coating... unless anyone here thinks I should prep the roof differently
I had a 1995 22' 21A Four Winds MH that I bought new. It came with an aluminum roof. The cab over developed pin holes from electrolysis, galvanic corrosion or whatever reason. The dealer covered the cab over with a fiberglass panel (filon) and pulled off the aluminum roof and replaced that with a rubber roof. That might be your best solution also.
I also bought (about 2 years ago) new rubber roof material for another 24' MH from an RV dealer who my son works for,it cost a little over $200, so it isn't, or at least wasn't that expensive.
