I am getting ready to spray epoxy on my actual project, but I have only ever done Etch, 2k, Base, Clear, and SS. So last night I grabbed a scrap piece of aluminum, went over it with 80 grit on a DA and decided to test out some epoxy primer on it. The reason I am posting this up is because I am unsure about the results.
I am going to list out the steps I took, that way if there are any issues you guys can point them out.
1. Cleaned the slab of metal and went over it with 80 grit on the DA.
2. Cleaned the piece of metal with some wax and grease remover.
3. Mixed the epoxy - 1:1 and stirred well.
4. Set up the gun - Finishline FLG3 with a 1.5mm fluid tip and HVLP cap. 22psi at the gun handle with the trigger pulled fully. (By the way, it is my first time using this gun.) I always used HF guns for the 2k primers and my Tekna for the base / clear.
4. Waited 30 minutes, stirred again and strained it into the cup.
5. Tested out the spray patterns and left the fluid control wide open with the fan pattern 1/2 turn in from wide open to tighten it up a bit.
6. Sprayed what I thought was a wet coat on the panel and took the pictures below literally 3-5 minutes after the coat was applied because it looked strange. Nevermind the trash, I did this out in the open (not in a booth). I was just trying to figure out how it flowed out and wanted to get a feel for how epoxy primer worked.
7. Sprayed a second wet coat after 30 minutes and then it started to look better.
8 Left it overnight and the below 2 pictures are about 18 hours after application.
It is now quite smooth to the touch, but orange peel is certainly there. I was just wondering if you guys think this is acceptable or if there are settings / techniques that need to be adjusted.
Since I haven't used epoxy primer before, I wasn't sure how it is supposed to work or react and I was hoping you guys could help me out.
