1964 Valiant "Get Runnin & Drivin"

on these older cars, seam sealer is not the product to use UNLESS you are stripping the entire body seams of the old stuff, then you could come back with 3M or equiv sealer..but then again, if you are doing an inner panel and carpet or mat will be on top...who is to know...again this would be more in line to total product change..
