joatmon67,
I'm in the middle of that nightmare right now, today, in an hour, on my third day. OY! VC-17 is great stuff, as Rich has pointed out. It's supposed to add a knot to your speed and bio-stuff just can't grab hold of it. One problem is that once you use it, you're married to it. Since it's very slippery, not much but VC-17 will stick to it come re-paint time. Also, the colors are limited and dark (I think). I almost went with it,then I decided on Pettit Hydrocoat. It's a waterbased, hard ablative that is supposed to be perfect for trailerables and it's supposedly more environmentally conscious do to the reduced VOC's. Either way, they are both excellent products.
If you're stripping your bottom first, I recommend a 3000 PSI pressure washer with a rotating nozzle. Mine took 85% of the paint off in a couple of hours.
