new air brush

I use Plastic Prep to clean the kit before airbrushing and wear latex gloves when airbrushing.  

i also noticed that now i have painted first coat that i have oil marks from my fingers will a tack cloth or maybe alchol take this off when i go to re coat? i still have to fill in edge line of wings and body.

You can always add another layer of a paint, but it's difficult to remove a paint. So, thin the paint and build coats.

Paint mixing could stand a whole book.  Flats are different than gloss, enamels different than acrylics.

Final coat may allow more thinner than first few coats.

I find the paint job always looks better with multiple coats using misty spray layers. It needs a 1:1 to 2:1 thinner to paint ratio in general depending on the paint you use. You have to experiment to find the right mix for you.
