I have not had great luck with primers andam still trying different stuff, although I have not tried the primersadvised here.

My last primer was Kiltz oil base stain blocker primer, and I had it tinted gray, I also thinned it and airbrushed it on. ( My touch up gun broken )

I built up my panel lines well and then removed the tape. The finnish was very rough feeling so I gave it a light sanding with fine paper. I almost lost my panel lines in no time, the primer coat was very soft. The burning in on the rivets did not seem all that good, again, soft paint?

Anyway, what I and trying now on my Topflite GS Corsair is : primed and sanded very smooth,cleaned ,then apply panel lines, Then build up the panel lines with 2-3 coats of my final paint which is Warbircolors, using my airbrush. This willput hard smooth coats over/ along the panel lines, then burn in rivets on the hard cured paint, then pull the tape, fine sand the surface alittle, clean, apply final coats of warbirdcolors.

I think this will work very well, It will take several days as I should let the paint dry overnight after every coat. I think I will end up withnice sharp clear panel lines and rivets.

What do you guys think about this approch?
