Well, I finally got around to spraying the liner in my tub yesterday. I went with the Duplicolor product, figuring at half the price of the Herculiner, it was a gamble worth taking. I can always buy a spray can or two more to touch up/add depth, if needed.
Anyway, I sprayed it in, and it did not work as I expected. I don't know if it was the gun (undercoating) I used, or my compressor, or what, but the stuff came out a lot thicker and "gloppier" than I thought it would. I shook the can for over two minutes before I started, but the material still seemed to have some "lumps." I had the compressor up to about 65 psi (directions say 30 psi minimum) and had thinned the product with some acetone, per directions. I thought I would end up with a smooth, flat surface, but it ended up bumpy/textured. It isn't so bad, really, as the texture gives it some grip. I used up all the gallon can of material, as it did not go as far as I thought it would (because it came out thicker). Maybe I should have cranked the psi way up. At any rate, it looks pretty good and we will see how it lasts. If I had to do it over again, I would probably roll it on, as you have much more control over where the stuff is going and how thick it will be applied.
Thanks to those who gave me suggestions and assistance with this.
