I'm planning on doing my underbody this spring. I wish I knew about POR-15 before this winter or I would have done it sooner. I'll be doing the frame, spindles, rear axle, leaf springs, lift blocks, and driveshaft. 1 quart covers 96 sq. ft.

I'm planning on using the Marine-clean, then the Metal-ready, 2 coats of POR-15, then top coating with Blackcote for a nice glossy finish. I figure it's going to be a lot of work, but it should last for a LONG time if prepped and applied properly.

Check out the website for info and application instructions:

Yeah that probably was it, it was too cold and the paint didnt fully cure...

I will just wait till spring roles around I suppose and I will re paint the driveshaft, and POR-15 my entire underbody... Thanks for the help guys!
