After a chat with the tech line in NY decided I should worry less about the temperature and more about the humidity. Its right at about 60 degrees for the high today but its about as dry as I have seen it in 8 months so with 60% humidity I went for it. The guy I talked to (didn't ask his name maybe Eric) said 60% was plenty humid enough for it to cure and that with it that humid the low temp should be ok. Obviously not ideal but better than warmer and wetter which is most likely the only other option this close to a rain forest.
My compressor is a mismatched bunch of compressor parts that I put together for free. It had a hard time keeping 40psi to spray with.
Its the same one I used for the raptor so I expected this. I did not expect the Montaliner to be so thick. You could really see it in the spray pattern as soon as it got down to 40 psi it would start spattering more than spraying. I highly recommend a cheap pressure regulator right at the gun so you can compensate for the quick drop in pressure if you have a questionable compressor like I do. A bit of fiddling kept the pressure where I wanted it for one pass around the tub.
Comparing this product to Raptor is really not fair. Its a much better product you can tell that just by how it sprays and how thick it is when mixed, you can just see the ceramic in it and it looks a bit like metal flake.
And I can say that with experience, this is my third product like this and my fourth project.
passenger side floor, the green is self etching primer and a spot where the raptor had peeled reveling rust.
Here is the driver side roll bar mounting this was the most rusted area and I had wire wheeled it and primed it three years ago. The raptor didn't seem to slow the rust much.
Here are some pictures of the texture and such sprayed at 40 psi or as close as I could keep it with my tools. at 60 degrees and 60% humidity.

so far very pleased I look forward to the cured final product.
