I just finished welding in new floorpans. Made them at work from 16ga galvanneal (being an Enginerd in a high tech facility is awesome BTW). I've read that POR-15 won't stick, unless it's all scuffed up and they're galvanneal, so if I scuff them, i'm going to remove the protection from it. I was planning on using POR-15 on the seams & welds and on the old metal.
Can anyone recommend a cheap coating to put on the new panels (inside and out)? I want to roll on a truck bed liner as well. Herculiner isn't available in Canada and I've read some poor reviews on the Dupli-colour bed liner. Any suggestions?
