Good luck - I know when I had to put things off for a while, it drove me up a wall. The por 15 I used on some rust spots worked well, but I was too cheap to use it everywhere, and being too cheap showed up when I put a bed liner down. Instead of breaking down for hurcuiner, I went with the duplo color stuff. It was only 25 buck per gallon. Now, it's cracking and peeling. I'm going to have to grind it all off and start again.
In any case, give some pics when you get it all going
