It took me 4 times before I got it right. I'm painting a '62 T-bird hood. (it's big). acrylic polyurethane paint. First time I painted it I got fish eyes. I thought that i had some contamination on the surface. Sanded it down and made sure the surface was clean. Second time I got fish eyes again. I thought that I might be getting water in the compressor tank. I drained the tank and sanded the hood again and installed a descant water filter. Third time I got fish eyes again. sanded hood again, Fourth time. Waited until the dew point was below 70 deg, and added some fish eye eliminator. Being gun shy I gave it a couple of light coats. Finally, no more fish eye. What do the pros when painting in high humidity?
We just paint in the south It’s humid all the time. Fisheyes is a contamination. I’d say the fisheye eliminator worked and helped more than the lower humidity. Fisheyes came from air tanks, lines, on the actual surface or just in the air. WD40, tire dressings, other silicone products can just be in the area and cause issues. Plus if ya had fried chicken or pizza at lunch and didn’t wash up good. A shop down the street can spray silicon products and cause fisheyes
Yeah pretty unlikely the humidity in the air caused fisheyes as Anthony said far more likely you have a contaminate somewhere that the fisheye reducer solved.
Did you change your air hose after putting in the filter ? Clean your gun? Next time you have the problem , sand it down & use a sealer .
I remember years ago when I couldn’t paint when it was humid because the paint would blush. Seems the newer urethane paints don’t have that problem like lacquer did. And, I agree with others in that there is some contamination in the airline or something that the fisheye preventer took care of.
l bought one of those handy dandy pour spouts to fit on my gallon can. Turns out they were made of silicone. Cleaned gun thoughly and used new gallon of paint. with no pour spout and it was fine.
I don't even store silicone products in the same shop as the car I am prepping and painting. Fish eye eliminator helps but not a cure for a contaminated shop. I had a moron spray the ceiling fan with WD40 because it was making noise. Guess how that ended?
So…probably shouldn’t tell on myself, but I will. When I was 18, I was working in a body shop as a helper that also let me paint cars on the side. I had painted a Mercedes and just needed to finish cleaning it up. I just happened to be detailing it in the detail area while the main painter was shooting a white Trans Am in the booth. So…seems the intake air for the booth must have been inside the area I was since that car fisheyed like nothing I had ever seen. Guess who got to sand all that down so it could be painted again?
You sure you aint the guy that sprayed my fan? I don't recall his Christian name, but we called him dipshit.
Not unless your fan was in Arlington, Texas in 1990 or so. But, that same name could have possibly applied to me on that day at least as far as what the owner of the shop and his brother (the painter) thought.
In the past when I used fisheye eliminator the gloss would fade away in a month or two. I never use it now. No silicones in my shop anymore. And no fisheyes anymore.
humidity will cause all kinds of havoc ....paint is so expensive now....I know a shop that just paid 1200.00 for a gallon of paint...
