What do you guys use on your vettes for preventive maintenance to keep a nice seal and so the seals won't crack/leak over time

silicone spray

I use what the "owners manual" says die-electric silicone grease

2009 Owners Manual also recommends "GM Weatherstrip Lube". I tried it. It's expensive (list $75 for SMALL bottle), runny, and doesn't seem to do as good a job as the dielectric silicone grease. It won't attract dirt like the grease, but it wants to run down the side windows and smear them.

I use Aerospace 303 Cleaner to clean the seals and 1Z Gummi Pflege Rubber Protection to condition them.

I use Malco spray cleaner. Then Malco PB-2. Same thing for ALL
rubber Vinyl and leather. The stuff can make rock hard rubber soft again!

Die electric grease.

That's the stuff I tried, and was highly unimpressed.
