Well, just finished shedding about 50lbs or better off the bottom. Cleaned and now painting with POR 15. I debated what to do and just decided to paint the bottom and undercoat wheel wells only. I can still paint it body color since the POR 15 is paintable.There is no rust left on the car. It also has the back half of a 4 door o it so there are some scars from that which I used seam sealer on.
