I just got done today sealing up my 73 Grabber with POR 15. This stuff is great. I sealed the insides from front to rear. It was dry within about 2 hours. This stuff was like putting on a fresh layer of 16 gage steel! My spray gun is soupe but it was a cheap one! Clean up on your skin is easy as long as you use a green bad and some elbo grease! I was wrapped up in a bandana, rubber gloves, goggles and paper breathing mask. It is some strong stuff. I'll be using a brush with some of the stuff Sunday or the next day depending on the weather. If you have rust this kills it in it's tracks. You can start body work right on top of it to keep your vehicle sealed even under any body work you do! It is a little $, but worth it in my book.
