I want to coat some areas of the belly with POR-15 before the government starts dumping carcinogens all over the roads this winter. I don't want to over buy the POR, it is pricey. My question; what is the coverage, in Sq. Ft. for a quart of this stuff, or how much did it take to do one drivers side floor pan within and without. (inside and outside)

I've done my floor pans inside and about 3/4 of the underside of the care with a quart and had some left over. It's pretty thin and goes a long way. Great stuff but as usual, its all in following the prep instructions. A quart will be more than enough and if you seal up the can, it can be stored in the fridge and last a pretty good while.

1/2 pint would do one side of the floor- it goes a long way. The hardest part is not to put it on too heavy. Try and put it on as thin as you can- it flows out really well

Thanks guys.

I think the age of the paint matters as well. I have bought a can that was thick and did not flow, and I have bought one that was thinner and laid down much better. In any case, you are better with the smaller cans. A one gallon would dry up on you before you could use the entire can and you are not supposed to thin POR 15.

I hope you guys are right, I bought a Qt. and I hope it will do the pans, sounds like it should be enough.
