Looking through a couple excellent write ups on side window installation, and everybody recommends the 3M window weld.
Cheapest I found it was ~$18 plus $5 shipping.
Seems like a lot of money to run a couple beads.
Any body use plain ole window caulk?
If so, how did it hold up?

Other stuff can work....but you need something that stays flexible. And whats $20 on something that keeps water out of your fusebox?

Cheap at twice the price. They make products that WORK. Would hate to use a cheaper product to find out that you now have to do it over again.

Thinking about replacing the windshield too.
This will work for both?
Hate to throw away most of a $25 tube of caulk!!

If 3M makes it and it's recommended, I wouldn't use anything else. Little known fact, 3M has a sports car club at their original location in St. Paul. I have actually autocrossed on their campus...

It is the same for both the rear window and the front. It's just butyl rubber, made specifically for this application. I found no reference in the maintenance manual calling out 3M.
It actually calls out "SOLBIT TWS" 8mm manufactured by Bostik "or similar".
