Are you supposed to put a second coat of POR-15 on? I didn't think that was a good idea. Once the chemical reaction bonds to the metal there is nothing left for the second coat to bond to, thus, it peels off.

I've used POR-15 for 10 years and I like the product. I haven't had any problems with it thusfar. The one big difference is that I haven't tried to put a second coat OVER an existing coat.
I'm still using it on my chassis on my 41 streetrod and I'll continue using it on my 72 C10 as well.

Just my thoughts,
