CHIP,
I've found, that with th entire "ALClad System" , each "layer " is super thin. I painted the Admiral in Their Black Primer/micro filler ( drying time 48 hours) , Gloss Black Base ( drying time 6 days - to ensure it had completely cured) , I then misted 2 coats of Chrome ( any more & it's gonna start to "haze" on you { drying time 48 hours} ) , misted 2 coats of the Aqua Klear Gloss ( drying time 48 hours ) I taped off the Grill & body Chrome & I misted 3-4 coats of the Transparent Red , 2 misted coats of Aqua Klear . All of these "layers" of paint are super thin .... in some spots it was too thin

& showed some blemish that was just barely part of the original finish. I was actually surprised exactly How thin the laters of paint are. It's lacquer based &I don't think it would harm the contact paper too much. For th simple fact that you are not saturating the paper with paint ??
With some of that inside painting you are going to "back" the Transparent blue . You could think about any of Their colors , pretty much any type of sheen that you are after.
I agee with

, I like that Aqua Kleer & it does seem to have a harder finish. You can see the difference between the Aqua Kleer & Future, Pledge, etc. I painted the Interior of the Admiral & shot 2 coats of Future on the seats & door panels. & Aqua Kleer everywhere else on the car.
Here's an example -
I've misted 2 coats of chrome
2 coats of Transparent Red , testing to see how it reacted with Low -Tact Tape ,
I think you can see how thin the coats are. You can see the reflection of the Running Boards in the Door panel !
I'm lookin forward to seeing th model !
