I've long used Americana Acrylic Sealer/Finisher spray; it's the only one so far that's actually sealed consistently for me on all types of plastic. For primer, I've been using Design Master, which is actually meant for plastics (results seem to vary, it bonds well with some plastics and not at all to others).
One trick I like to do is paint up my figures, then hit them with a heavy coat or two of the sealer. I then go back and paint over that. This serves two purposes:
1. Provides a sealed "undercoat" should the top layer chip;
2. Gives the top layer a "flat" look better than if it had sealer on it.
It's not a perfect method, but it has saved me a lot of headaches in the past. Of course my figures are rarely handled after I put them on display, so this may or may not work for you.
Another thing I like to use is Model Master's Acrylic Brush-On Sealer from Testor's. Only tip I have for that is--wait at least 24 hours after you paint something to add the primer. I seem to get the best results that way (that is, it doesn't end up washing the paint off as it's applied.)
do you mean wait 24hrs before you add the sealer? im confused as to why you would add primer after paint......
for drastic repaints like the corps figures you really should give enamels a go! i know it seems crazy, i thought it was myself a week ago but it really works! take the figure apart then use primer 1st (mr. hobby metal & plastic is the best ive found) then spray the whole figure minus head if bare skin with enamel red (2 or 3 coats, dont go to heavy) then paint the detail over that. you have to leave it to dry for a few hours (over night is ideal) but if you are working on a few figures @ the same time this is ok.
it drys really hard, this is a arctic red shadow im half way through & no paint rub!
