primer before airbrushing?

ace hardware NOW gray. bottom of the can can get gritty so it gets labeled armor and i crack a new can for ships and planes. i airbrush with acrylics.

Rust-Oleum American Accents Ultra Cover huh? I might try that over Krylon. I want to do away with doing multiple coats. I used Krylon Satin Black using multiple coats and ended up with orange peel on part of the aircraft wings. Not sure if it was because I did it back in early May outdoors with the temps in 50s sunny with an occassional wind gusts.

I alwyas prime. Depending on the main color of the finished model decides what color primer to use. White primer for light colors, black for dark colors and grey for medium colors. Priming helps to see more clearly those fine details you need to paint, highlights any areas you need to pay attention to, provides a better surface for you main colors to adhere to and sometimes helps to fill in small gaps and seams and hide them. My normal primer is krylon in a spray can but recently I started using Rust-Oleum American Accents Ultra Cover. It provides 2x the coverage so multiple coats are not needed. It works super great but you have to be cautious not to overspray and fill in those fine details.

I guess it all depends on the person. Thanks - I will look for Krylon primer tonight.

I almost always prime. My normal primer is Krylon primer in a spray can.  For the smaller parts I prime the whole sprue.

I also prime. Have been using light sea gray enamel from the Model Masters line recently. Funny too, its almost an exact match to RLM02 also.

Yes      Tamiya or Mr Surfacer 1200

unless I am doing multi media stuff- resin, PE, etc. I usually do not do a primer coat. Especially on aircraft builds. Unless I am using certain acrylic paints that have very poor adhesion qualities. Then a primer coat is required.
