Ive searched and read many threads but still not sure why im having an issue. My car was freshly painted, ALL the body lines and gaps are perfect. I installed new Softseal door weatherstripping for my 67 and my doors wont shut. I thought maybe its new and keep pressure on the door would help it seal, but no luck. I tried Metro weatherstripping and the same problem. I read a thread that the plastic nipples are only guides and should not be used, any one hear this before? Any help would be appreciated.
