Can anyone recommend a brand of weatherstips for my 81 camaro? I bought a set of OER weatherstrips and after installation you have to slam the door to close. they are really thick and stiff weatherstrips! I called OER and they said try a heat gun on them or lay them out on the asphalt to warm them up! so they went in the trash! I'm looking for a set that will fit nice and the doors close easy! Help!!!
