Determined to make the most of my time off I went back at it again today. And today was a much better day. The folks at KBS credited me for the congealed paint- kudos to their service dept. Turns out the stuff I had already (Rust Seal) is sufficient as a chassis paint. The top coat is only needed to protect against long term UV exposure. So my chassis painting is all set. I also applied more of the semi gloss paint on the fire wall and interior.
I still have a few small parts to paint, but the major part is taken care of for now.
