After the POR-15 dried we ruffed it up with sandpaper, then wiped everything down with tack cloth to get it clean. The Herculiner adhered great. So far so good anyways. It isn't as high quality as getting it done by Rhinoliner, but I think $39.99 as opposed to $500 is a good price difference!
Thanks for all the compliments on the roll cage! Hope to be installing the rest of the interior this weekend. I will post some more pics soon!
