I'm a proud new owner of a 91 K5 with only 63K miles. The truck is immaculate and was garage kept by the original owner. I'm truly blessed. I was wanting to get recommendations on what to put on my interior dash to keep it from cracking in the sun. Also, I'd like to know what to do to my window weather stripping (Particularly the rear exterior weather stripping) to keep it from cracking and deteriorating. Please feel free to email me if you prefer: my email address is email@example.com Thank you in advance.
