Better late than never, and after a good soap, water and a 3-M scrub pad it was time to repair, prep and paint the mid-90's YJ hardtop.
I gave it a going over with coarse sandpaper to knock down all the high spots of the stippled texture ... the ones that grab dirt and holds it ...
I got a fiberglass patch kit went to work ...
I laid a piece of 'glass on the inside of the roof to cover a bunch of drill holes (a CB?) and after it set up I snipped a bunch of fine glass fuzz and filled in the holes from the top as best I could.
After that set up I sanded this mass down and then applled small 'glass squares to smooth everything out.
The first pic shows a heat lamp on the laminate seperation on the hinge mount area. I opened up the crack in the lift gate door way and shoved a bunch of resin in with an epoxy brush then clamped it down. The heat makes the resin set up a lot faster! Actually, I've been told that the calalist causes a heat reaction and this what actually makes the resin harden!
Putting the top of the hatch on a creeper with an old pillow and a couple of blocks made of folded cardpaper worked great at holding the top at a good painting position.
The best tip is the paint I found.
It is SEM brand Color Coat #15103 "Super White".
(A misleading color name as it is a little ivory and their "White" is actually the very bright white.)
This brand is a "flexable coating" for plastics and vinyl that "changes or renews color".
The best thing is its so close to the OEM color that I had a hard time seeing what I had or had not painted! The job wasn't near as hard as I thought it would be. Just takes time ...
