jibber,

Thanks for the tip, I will need to give it a try.

Kentucky, I use Army Painter primer rattle can, it goes on smooth and covers evenly. It adheres very well to PE and is relatively cheap in large cans. limited colors though.

I use Mr Metal Primer and haven't had any problems with it. It's practically water so it won't fill anything at all.

I find that acrylic primers may not adhere very well as I had some lifting when removing masking even with proper surface prep. I like using decanted Krylon primers in my airbrush for excellent results, specially on pe. Tamiya's primers are equally excellent too and their rattle cans have a very fine and smooth flow.
