UPOL Raptor and similar coatings

I am getting far enough along on my 72 project to start thinking about the paint process. First, this is not a show or original car. I have resurrected it from the dead rust pile and have take a few liberties to build the car that I want. So...

The car will be painted back to its original Tangerine color. I have accumulated enough UPOL Gravitex to correctly treat the underside of the car. The plan was epoxy primer, gravitex and then paint to color. Some areas will be black and some will be body color - basically an interpretation of the correct 72 painting scheme.

Now, Here is where my question starts. If I coat with my scheme (primer, undercoating and then paint) this amounts to 3 steps and 3 different materials.

I recently came across some of the tintable undercoatings. Examples are Upol Raptor and the Monstaliner. Both of these can be tinted to match any color. The difference is that the tints must be binder free. The difference which I like is that the coating is color all the way through and I would only have to have 2 materials and coating sessions. This saves time and money.

I orrdered a sample patch of the Monstaliner and the texture is similar to what the factory product would be. I can get the Raptor tinted local at my jobber shop.

Has any one used the Raptor material? Does it dry rock hard like a spray on liner or remain slightly rubbery/compliant like Gravitex?

Was the application similar to the Gravitex? I will be using a Upol undercoating gun and am decent at it having coated a fuel tank.

Thanks for any suggestions/experiences you can provide. Just trying to save on materials and time here.

Thanks

Jamie
