1970 gs ...best glue to use on ram air foam on air cleaner please... I did a search did not get the answer
Most guys take them off for regular driving, and put them on for shows so they don't get smooshed. So no glue in that case. If you want to glue them on, contact cement, or weatherstrip cement.
