So I am extremely pleased with the end result of my experience with painting my blower. The paint seems durable, smooth, consistent and looks professional. First things first I prepped the blower with un-diluted degreaser and a tooth brush. Then I cleaned it with a cloth and isopropyl alcohol, and lastly I blasted it with non-chlorinated brake cleaner finishing it off with compressed air afterwords. Next once completely dry I sprayed the entire blower after taping it off with "SEM" brand Etching Primer which etches aluminum and creates an extreme bond to the surface with a chemical reaction. I laid down maybe 3 even coats allowing 15 minutes between each coat. This primer is dry to the touch in 5 minutes usually. I used a heat gun and gave it more time for consistency. Here are the pics of the blower after primer, and I must say the primer laid down extremely smooth with no runs prep is everything with this project.
Next I Put the primered blower in the oven at about 170* to warm it up before I sprayed it for better results, although the primer is going to make all the difference in the world. I sprayed a heavy coat moving back and forth first then up and down followed by diagnal movements holding the can about 12" from the blower. It sprayed on smooth And about every minute or so I would turn the can upside down and spray until clear gas came out to clear the nozzle. I took my heat gun to the blower and watched the paint "wrinkle after about 15 minutes. Remember every coat you lay must be heavy for the wrinkle to take effect initially. I laid down 2 more lighter coats using the same technique. Then I put the blower in the oven @220* over night. This is what I pulled out in the morning. The flash Kind of washed everything out but I am blown away with the results!
From the little time I spent inspecting it I have yet to find any inconsistency or runs. Everything seems to be even through all the cracks, corners and fins.
