Got 'nother one for ya.

The stock weatherstripping on these cars is kinda skimpy, about as thick as my pinky. I was wondering if there's a more hefty replacement out there. GM stripping seems be be as thick as my thumb on some of their models

I don't care if I have to slam the doors a little harder, I just want a tighter fit.

If no options exist, what can I use to clean and preserve existing strip - it's not torn anywhere I just want to restore it's showroom pliability.

thanks,

Chris
