Hi guys! I picked up a 10' pop up camper that I just tore down to the frame. Before I start my build, I went through and re-enforced some welds and supports. I'm thinking I should coat the frame with some Por 15 before I start building on it. I've never used the stuff so I'm wondering how much of the stuff I should order to do my 10' frame. They sell them in a 6pk of 4oz cans which may be the way to go cause it sounds like the stuff hardens once you open the can. I was wondering if this was something that I can do over the course of a couple days or do I need to put the Por 15 on right away after I use the degreaser and metal prep? I was hoping to wire brush/wheel all the loose stuff off one day, maybe do the degreaser+metal prep one day, then Por 15 another day?? Maybe I could do half the frame at a time...free time is minimal (2 kids, oldest is 4yrs old!!)... Thanks for any advice or tips!
