Learning to Paint: Laying down color

Before jumping to the color base coat, I decided I need to spend more time working with the gun and attempt the primer again. I diluted it 3:1 instead of 4:1 and made sure I had the paint feed all the way open. I got slightly better coverage, but unfortunately there was still too much texture to the spray.

At left is my second attempt at primer, which still has noticeable texture. At right is a valve cover sanded with 400 grit.

Frustrated, I turned to the internet. After watching a half-dozen videos, it became apparent that to get good results with the turbine sprayer, you HAVE to use the pressure cup. I was using a PPS 2.0 disposable cup liner system. There is actually a 3M PPS pressure cup that uses the disposable liners, but I only had the gravity feed cup. I decided to use the stainless pressure cup that came with the gun for the color round. It made a HUGE difference.

I mixed up the Bonneville Black Cherry. I was really excited about this color, and I have debated whether or not I should paint the entire car with it.

The paint looked very black, but as I stirred, the metallic red began to appear. However, as I sprayed it on, it looked black with a hint of plum. I did some parts with what I would deem a regular coating and some I went heavier to see if it would affect the color at all. However, as it dried it seemed to become more of a bronze champagne? I’m not sure how to describe it. The photos below required the camera exposure to be pumped up to see the color because without direct sunlight, it looks more or less black.

I learned some important lessons this round beyond just the fact that I have to use the pressure cups.

Lesson 1: Laying the paint on thicker did not improve the color, it just caused solvent popping.

Lesson 2: I’ve got to stop painting on a table. The first round of paint keeps drying on the plastic sheet, then it cracks off and blows dust up onto the things I’m painting.

Lesson 3: If I have to flip something I’m painting, give it extra EXTRA time to cure before flipping or it just screws up the paint I’ve already sprayed.

Lesson 4: Don’t remove the coveralls until after you clean the gun or you will probably splash thinned paint droplets all over your clothes.

The valve covers, which were stacked higher than everything else and don’t require flipping were the only pieces that came out “good.” There’s one very small run on one of them, but I can’t decide if it’s worth fixing or not. The oil pan was great until I went over it with a SUPER thick experimental coat to see if I could get more of the red color to come out. The red did show while I was spraying it. It then dried the same color as everything else but with lots of bubbles from solvent popping. I think I’ll re-sand and re-spray it. The air cleaner lid and base both fell victim to having cardboard stick to the bottom side while I painted the top. The snorkel was sitting right on the plastic, and it has plastic coating the entire bottom side now.

I will definitely find a way to hang my parts to do another color coat before I move on to clear coat.

One thing I have decided, I do not want my entire car painted Bonneville Black Cherry. I will not order the paint for my car online. I need to find a local shop where I can lay my eyes on the real colors before I commit to spraying the car with it.
