Just starting back on a new build after much time.
I am priming the 1st parts of the empennage with some concerning results.
It is amazing how much you forget when you don't do something on a routine basis.
Any suggestions would be appreciated.
Here are my steps:
1) Surface clean with acetone and a scotch bright pad.
2) Surface prep with Prekote in accordance with SOP, (2x), rinse, repeat if necessary,
3) Air and/or towel dry
4) Air apply 2-part Akzo Nobel with 3M Accu-spray 1.8mm head @ 95 psi line pressure, 30 psi open air flow at gun, and 20 psi full open with fluid at gun.
My issue: this results in a surface texture equivalent to 1200 - 1400 grit sand paper.
I'm looking for a smooth finish - I'm thinking I have too much air and not enough fluid flow.(?)
Thanks in advance for your help on this.
