I have seen some 32, 33, 30, & 31 Fords which use hideum between the fenders, splash aprons, and etc. What is the actual reason to use this? Some of the show cars I've seen have NOT used this. Would you strictly use this hideum if the body panels do not line up perfectly so you hide that? I'm trying to decide as to whether or not to use it, but I would like to know the reasoning behind its useage.
