Thought I'd add some more help, with prep for painting.
I found it best to Wash the parts with a liquid detergent(like dawn) and a scotchbrite pad.
Rising them well, then Lightly wet sanding all the surfaces that would be painted. With the appropriate sand paper for wet sanding.
Then wash and dry them thoroughly.
Used
Lots of white masking tape too.
Using light coats is best.
May take 6-10 coats depending on how heavy they are and temprature.
Try not to paint them in full sun.
This will cause overspay and may not produce a desired effect.
Which if you do get runs or fisheyes Leave it !
Let the part dry thoroughly and lightly wet sand the effected area(s), then clean the surface well before touch ups.
After paint has dried for 6-8hrs(or what recomended on the paint or clear coat) You can begin to clear coat everything. 6-8 thin coats, this will help keep the parts shiny and protect the paint from chiping.
Heres are some more finished picks of my GA's.
