Final push towards the end...door weatherstrips - ZR-1 Net Registry Forums

Corvette95 · 01-06-2021

Almost done with this 2 year restoration. I replaced the drivers door with the last NOS weather strip I could find, it came in not in original foil GM wrapper...installed, door closed with one finger it has already began to crack and disintegrate even without driving, replaced with CRC now hard to close.. Passenger door, installed 2 different brands (no NOS to be found) door has to be closed hard. There is a bind near the side of dash, a pillar section. I have removed and adjusted it, adjust new A pillar weatherstrip, lubed the weatherstrip on body and door, still take too much effort to close.I can't see if it is the A-pillar weatherstrip, door main weatherstrip, windlace or even the door panel may be installed a little to far forward. I have tried to adjust all of these with no change. Same thing with window down, also there is no weatherstrip . Left it in sun for a few days -temps in 0's here in Bama, no change. I have searched this extensively, the most suggested repair is sitting in the sun but I don't think it will help. Gonna try removing windlace and try again today. Does anyone have outside the box tips? 1990. I think the door panel has a little room to move a little and I have tried that too. Tips appreciated.

Last spring I replaced my door seals and the "B" pillars and halo hatch seals.

I had problems getting in touch with CRC, so after I had finished (another C3) using Wilcox, I went with them for my ZR-1 seals.

Well, yes, the doors had to be shut on the firm side - at first. But, now less firmly, now that it has been 8-9 months since I installed it.

I did use CRC rubber when I replaced my windshield, and the rubber was very pliable compared to some other rubber sources. And, the Wilcox products were equally pliable (like the CRC) rubber. (I've heard that Wilcox sources their rubber from CRC, which if true might explain why the texture is "the same"(?).)
