I'm having trouble getting repeatable sprayouts. I haven't sprayed dbc in 10 years but never had a problem like this. I have little experience spraying white but I can't get sprayouts from day to day match using the same spray technique.
Tekna gun with 20psi regulated on the gun. DBC 1:1 with SPI 870 (a couple times I added 2102-4 but wasn't paying close attention on early sprayouts)
I've done white epoxy sealer, grey epoxy sealer, black epoxy sealer experiments. Complete coverage in all cases with 3 coats.
Some of my cards have more yellow and some are more white. Looking for ideas as I need to get a consistent color so I can decide if I have to tint it with more yellow.
Some of the things I've tried.
1. 3 sloppy wet coats leans yellow with some slight color changes on the edge were the extra paint ends up. I don't spray this way.
2. 3 normal coats is more white and more consistent.
3. I try to do 3 sprayouts at a time shooting for the same results. These three usually all match. Twice I've started a 4th card about the time I spray the 3rd coat on the others. Both of these 4th cards have gotten 3 coats and both are usually a shade yellow compared to the original 3.
4. I did #3 above yesterday and today and yesterdays is more white than todays using same technique. The 4th for each is different.
5. Early on I did the 2 coat/3coat/4coat cards over the white/black/grey sealer and had very inconsistent results that didn't make sense.
Would activator change a shade?
I wasn't consistent on clear times ranging from 1 hour to 12 hours and didn't take note. I will be from now. When I do the car and parts base will sit overnight. Does this affect the shades?
How critical is white paint for repeatability. I planed on spraying doors/front/rear fenders together but this color has me thinking it needs to be jammed and sprayed together. Any thoughts or things to try would be helpful.
I think I want to tint the color more yellow and then the next sprayout is the right color. Very frustrating.
