I attempted a seal replacement on my alpine windows while headliner is out and I blew it. After over an hour try8ng to get glass to seat in warmed seals, i just couldn’t get top to seat. Glass kept slowly easing out. Could never get the seal to correctly turn over so glass sits in correct position— possibly do to roof being slightly bent or slightly due to britpart seals. Finally used silicone lube instead of dish soap and on first attempt, it slowly popped back out nd boy was it slippery! Vroooooom, right onto the ground in a million pieces. Duct tape now employed while I wait. Yes. I cursed. A lot. When we did Dave’s, this went way easier... Genuine seals ordered as I don’t want to screw around. I’ll also compare seals for everyone. I’m not blaming the seal outright as I don’t have a genuine to compare it to, but I’m not happy. i always hate when I order OEM and it comes in a blue bag... glass and seals both 4mm, as I know there are other sizes. Ordered 2 windows to make sure the match and now I’ll have a spare (hopefully, I won’t need it).
