RE: Spraying Latex Paint with HVLP Gun
I sprayed my first "real" parts tonight and so far I am happy with the results. Below are pictures of tonights painting session. I used the same method of mixing the paint as describe earlier and the paint mix was right on again. As Campy mentioned above the article is a great starting point in my opinion and somewhat of a guideline. Like I said before, practicing will help yield better results and allow you to very certain steps towards your liking. I noticed Campy made a mention he does not use the heat gun. Interesting because tonight I only used the heat gun once and that was after I felt enough coverage was on the parts. And after I used the heat gun to just take the sheen off the wet paint I sprayed another 2 or 3 light coats to kind of even things out. Also, the article mentions only spraying 2 or 3 coats but I found I have to apply about 6 to 9 coats before I am happy with the coverage. Still though the process goes pretty fast because I am only waiting about 5 minutes between coats. And I'm sure I might be able to cut down a few coats if I was a little brave and tried to spray heavier coats.
I also checked my previous sprayed test parts today and they still look real good. The latex really settles out nicely and evenly. I plan to wait about 6 or 7 days and then try spraying water based poly on them to get some practice. I use Kerosene for my turbine jet and I want to see how the latex with and without poly reacts to it. Even though I plan on spraying everything with poly anyway.
Picture 1 shows my gun.
Picture 2 was taken after the first coat was sprayed.
Picture 3 was taken after 4 or 5 coats.
Picture 4 was taken once I was satisfied with the overall coverage.
The parts sprayed tonight were my Super Reaper nose piece and main hatch. The hatch will be partially yellow and blue.
