Ok, so I'm totally new to iH8MUD. I drove my TLC from Arizona to Alaska. Imagine my astonishment when I discovered that there are no parts for an Diesel Aussie HJ47 in Alaska. I decided to rebuild it and have been stripping it down. I'm now down to the chassis. I went to the store and bought PRO and want to make sure from the experts that I'm not missing any steps before I encase this baby. I scraped all the 30+ years of crud off. Then, wire brushed the entire thing, de-greased it, pressure-washed it, sand-blasted it, and ready to coat it. Do I need to adhere any primer or can I just do the POR? Also, how do I get the POR inside the frame? Or is it even necessary?
