In Tech school , in an automotive bodywork and refinishing program. I would say painting and the whole prep process covers over 50% of our class time.
I am using my Sata 4000b digital HVLP for Primer, sealer, base and clear. I read somewhere here that the 4000b hvlp is best for base. I have the original factory 1.3 tip on it. I was using the RPS cups and then switched to the 3M pps and Sata metal cups. The later 2 cups deposit more material. I think I might go back to the RPS .
Every single paint job requires me to spend a lot of time hand wet-sanding with 1000, 1500 and 2000 grit. Now I know typically a decent painter's clear and base should be good enough to not require wet-sanding.
I tried out various settings on the gun . The oval shaped pattern tends to spray more and wetter on the top of the oval than the bottom and center. I also have to hold back further than 6" to get a wide enough spray pattern.
Is there any setting you recommend ?
- How many turns of the fluid control knob (if the base position is the knob being turned in all the way in)?
- Fan pattern control: Turned all the way clockwise or counterclockwise?
- Air micrometer: the middle setting or the wide-open?
I am just not getting a decent finish with Base and Clear.
Should I just get a different gun for Clear and keep this for base only?
