I have hand blocks that separate the boys from the men. These wave you see could have been caused mostly by one of two things, or both. First, a large flat primer surface should be blocked with a long flat block getting as far across the panel as you can while keeping contact with the surface as close to 100% of the blocks area. From there your sanding pattern should resemble an x. Depending on the primer, and coats, (I prefer 3 coats then sand), and how straight the panel is, you might go down to 180, but if that’s the case you need to just redo your body work. In theory one would use a block larger then the panel, but that’s not practical.
If you do not have experience, don’t use a power sander. You can make waves all to easy picking up a DA and sanding your car. Most likely you won’t see it till it’s painted.
I sanded new parts for a year at my first job, I had to prove myself to finally use the DA. Now I wet sand new panels, it’s cleaner, safer, and just as fast as a DA.
Well I am 😆 unless were talking a 350 hood or bed side, but I still wet sand it by hand. Any grit over 280 works better wet.
I am spraying Dupont CroMax, and using mostly Nasons production clear in a positive pressure cross draft that peaks at 100f when baking. The owners don’t want to send anyone to school, they are way to cheap. They are charging a customer to repaint a bumper that they shot a year ago. It’s a raw lexus bumper that the old painter used only a adhesion promoter for the base. It took me 2 mins max to blow of the entire bumper. The shop is second to most, and the managers know nothing. I have been asked a few times to buff out some scratches that are down to the metal/plastic, and they keep trying to use just waterborne base as a touch up paint.
A quality rating to the work that I see has left the shop is 2-3 most. We don’t even have all the proper reducers for clear, to spray at the current conditions. 60% humidity, and 90 plus degrees. Almost everything we shot this past week got solvent pop, and they only let us re-shoot to mirrors.
I spoke with the rep, he said I’ll come shoot something with you. That was last month, and it still has yet to manifest.
My main concern is shooting the base, 1.5 wet coats with no flash I get it, but that could translate a millions ways. When I lay down a wet coat, it looks like crap, but dries out nice. Which is what the rep said to do, the other painter there, puts it on like it looks and does not adhere to the 1.5 wet coats rule. Basically shoots it like solvent. I am so lost, with no master to guide me. I just want to do it right, and not just so is does not come back, but because I like to take pride in my work.
P.S. thanks for the replies, and warm welcome!
