I had great results with Raptor over aluminum everything got sprayed first with Acid 8. I didn't need a high build epoxy primer. When I do my tongue box I am going to use epoxy over baltic birch then epoxy primer and finish with Raptor. The guy at the pint store is confident it's a good way to go.
Found a few pics
You can see the fine texture, the disk is an 80 grit. My texture is around 120 grit sandpaper. I used a cheap HF HVLP gun with 1.8 tip and had the pressure up near 50-60 psi. I did black and tintable. The first auto paint store was I went to and got the tint from was clueless, my Jeep's paint is a pearl. I gave them the code for the paint and since it is a pearl it is expensive and wouldn't tint the Raptor right. I ended up going off color chips and am close. The other paint store I have been going to said said you just add the tints and not any other fillers or binders to make paint. Then they add a few drops of white if needed.


My neighbor said a co-worker of his just had his G Wagon done and it doesn't look nearly as good as my tear. I don't like the texture you get with the standard gun that comes with the kit. It's to rough for my liking. We'll see how well it holds up, but from what I have see and read it very good.
