Hello everyone here at this forum.This is my first post so i hope I don't embarrass myself. I just retired from my job as a electronics technician and have started a project on my 94 chevy truck. It had a few dents and the old paint was fading out.I repaired the small dents with body filler,sanded the filler with 80.180,and 320. I used guide coat to make sure i did not have any high or low spots. After taking care of the dents,I than sanded the complete truck with 400 grit. I made sure that there are no shiny spots on the body at all. Looks pretty smooth now. Now,I am getting ready for primer so here is my question? I am using a 2K urethane primer along with its activator and reducer. Its a 4.1.1 mixture. I have a gun that has a 2.0 tip on it and I also have an extra tip that is 1.4. I am going to use the 2.0 for the primer and 1.4 for base. I hear about spraying medium and wet coats.How is this done? Are this coats accomplished by putting more or less reducer? Can someone please explain this to me. Also,is 2 coats good enough or should I go 3 coats. The primer is a high build primer. After I finish the primer,I want to let it set for a few days before wet sanding with 400. What do you folks think on how I should tackle on this primer job. Oh,the sheet on the primer says to apply 2 full wet coats at 40psi. My gun requires 5 to 6 CFM and my compressor is rated at 6HP at 11.5 CFM so i think I have enough air pressure to do the job. Need some advice and or opinions please. Thanks to all for your help.
