1963 Dodge Dart GT convertible rubber request

You have a Great looking car , but they LIED about it being the last top you will need unless you plan on kicking off after about 10- 15 years. especiallyif you use it a lot in the hot climate that will fry the vinyl or canvas top out Stayfast is called cloth, and still bonded to vinyl to be waterproof,I do help make convertible tops and leather interiors. 7 years is normal life on vinyl(or stayfast cloth) that's out in the sun and shrinking + 7-8 before being too stiff to raise and lower correctly.

I ordered my seal kit (7 piece one) from metro molded products. softseal also makes the stuff too.
