DIY sliding window leak permanent repair

Recommended Posts

Preventatively did this method on my ‘23 this past Wednesday. Thanks for the detailed guide and providing hope this won’t be an issue like it was on my ‘21! 

Couple notes on the spoiler reseal:


1. Those 2 lonely seals they include are only on the 2 yellow clips

2. the threaded holes for the 4 outboard bolts seem to have embossed rubber washers on the standoffs, which actually seem pretty good. I applied sealer anyway. 

3. I removed all the body plugs, applied light sealer to them as well. Taking no chances!

Just finished my ‘19 Silverado that had several minor leaks. Total of 5 cracks. 3 were fairly large. 
I have done lots of caulking on several home projects and when I built engines.

 I laid in a goodly coat of premium clear silicone and top coated it with the w/s sealer. I can’t imagine how it could leak. 
my only reservation (after putting it back together) is I didn’t put any sealer around the two plastic alignment pins nor the four bolts.

 I honestly didn’t think about those alignment pins….The bolts have a built in seal so less concerned about those.


I just figured out the pins wouldn’t need sealer…
