Hey Doc, if you do another solid paint job I highly recommend this stuff:
$9.90 at the green shed and dried very nice!
I used these on my Star Wars ST jr and i'm super happy with the application and drying.
I started with 3-4 coats of primer, sanded flat and primer again and no more grain.
Then only added a couple coats of coloured paints and looks awesome.
I'm trying out adding a clear acrylic coat on top, and so far looks all happy.
Colour range is very nice too.
