Yes,he's using a larger size olympic rivet. We have a 1971 soverign. And yes, EVERY seam is vulkemed, especially that area in the rear bath that rots out the floor. Every rivet is PARBONDED, front and back. We keep thinking we've got all the leaks. And then get 3' of rain and discover more leaks.
He uses an air powered pop rivet gun, drill out old rivet and clean up both sides well then parbond both sides and then pop it. I found out many seams were done over by PO in a VERY poor fashion and so leak. We really like the end caps on the inside done in a petal fashion with many smaller sections of aluminum. I think it was a 50's style.
Healthyhomes.com has a really neat example of it. And we were impressed by the elegance of it. He says now not EVERY rivet will be replaced...snicker,snicker. : )
Does anyone know what year that petal style endcap was used? Also our 1973 owners manual shows a picture of the interior ribs totally painted with some sort of sealant paint? something..sealer paint? Does anyone know? At this point with the trailer satripped, I'm all for doing an interior sealer coat before the aluminum bubble insulation. My husband says that wouldn't stop the leaks. Any comments on this?
Also we got the first of the solar components today the prosine invertor (pure sine wave) 2,000 watts and a bunch of parts.!! I'm impatient to move on from leaks. suz
