I bought this dolphin easily 10 years ago. It was in pretty good shape, but there were a few minor leaks in the cabover area.?
As the area of the cabover was prone to leaking, I decided to take a drastic step and removed the window, sealing it with plywood then fiberglassing over it. I also decided that some of the corners, between the wall and roofing metal, had water leaks so along the ply had puffed out from water expansion. There were spots where the corner metal did not fully cover the joint. As we were fiberglassing in the front window panel, I decided to fiberglass over the corners.
Here it is, many years later. I've pulled the tarp off with the intention of getting Dolphin on the road. Of course, I can't get it started, and it's been diagnosed to be a fuel pump problem, but the problem I'm here to ask about is there has been moisture that has gotten into the camper. I'm wondering if it's from where the fiberglass covers the metal corners, as it's impossible to tell whether it's 100% sealed. Though we put 2 coats of Kool Seal on, the Kool seal has come off in spots.
I'm wondering how to seal off roof.?
1. Do I need to remove some of the Kool Seal so anything I apply is on bare metal/fiberglass?
2. Should I get a can of Dicor RP-CRC-1 EPDM Rubber Roof Acrylic Coating Part 2 - White, 1 Gallon off a washed, cleaned roof. Can I se the Part 2 without using the Part 1?
3. Should I just use Dicor 501LSW-1 RV Rubber Roof Sealant Self Leveling Caulk where I think it needs to be applied?
4. Should I just run RV Roof Tape White along the edges where the fiberglass ends on the metal roof?
Any suggestions or advice would be greatly appreciated.
Also, I removed the AC and replaced it with MaxxAir, using new gaskets, so I don't think the leaks come from the open ports. I think it's the Kool Seal.?
