Hello,
After aquiring a 77 palm beach, the rain "Florida"!!, started getting into the coach. There were obvious leaks due to the windows needing re-sealing, and a few leaks i could not find.....
We are redoing the roof panels , decided on formica sheets, because you can get so many colours, patterns, and also because of its strength.
After i took some of the old card panels down, i noticed something strange. In various places where fitments were screwed into the roof from above, the foam insulation had been forced out of place, or was totally missing with sillycone that was not doing anything at all !!!!. So basically in various places the water was finding a path inside, running down the screws.....
I decided the best way of stopping this was to strip the foam away from any screws i could find and respray with insulating foam sealant. The theory being if you seal the screw area and the screw still allows water into the fixing hole/s, it cannot go anywhere because the foam sealant stops it getting into the roof space. It may pool a little around the screw but has no acess into the vehicle.
I did wonder when fitting new screws if one should spray foam sealant into the screw holle so it would expand and fill any void....., perhaps better than sillycone because it expands.
Well i would appreciate any comments on this issue, and if anyone sees a problem with this idea please put your comments up.
