Thanks Brian! I have been using prep step which is a degreaser and prep agent to promote adhesion of the zero-rust chassis paint. Prep step I thought about using phosphoric acid but when I heard so much talk about the debate of whether or not you should rinse the acid off before painting or not just discouraged me and I ended up using the prep step which has a neutral ph level and states not to rinse before paint, it was less steps and I like less steps! The underbody starts off simple but next thing you know you're picking at things you originally were not going to touch and then it feels overwhelming.
Thanks for the support guys, maybe I will just keep taking pictures and post them to keep me going strong at this. I wonder if I should start a new thread for updates?
