Primer on Priming
Primer - I use a few different brands, Krylon, Velspar and Duplicolor. For terrain projects I switch back and forth between Krylon and Velspar. Why two different brands, simple texture. Krylon primer has a little smaller droplet size giving a smooth finish at almost any spray distance. The same cannot be said for the Velspar. I haven't figured out if it is their paint mix or just the way it reacts with the air but it is the easiest to get a sandy/fuzzy texture of any paint I have ever used. This is a good thing when working on terrain like walls where you are going to drybrush a large area. It is consistent enough from can to can that I can control the level of fuzz by changing the distance of the spray. Very nice. The last one I use isn't really a primer but a combo of 2 products, first up is the adhesion promoter and the second is the vinyl dye. These are by Duplicolor and since discovering them I am never going back to regular primer. First off the stuff sticks even to resin and won't chip off. Second it doesn't fill in details even when sprayed on heavily. You don't need to spray it on heavily to get coverage. The dye is heavily pigmented and covers in one spray. It isn't effected by humidity. Finally it reacts fine with plastic glue so you don't have to scrap it off when gluing. Probably the only down side is it a little slicker than regular primer. I have only had issues with this when using an airbrush and GW paint.
Nozzles - Even with the right paint the nozzle used for spraying can really effect your finish. There are 2 major spray patterns you have to deal with, circle and line. Most cheap cans will have a circle shaped spray pattern. This gives a dark ring around the outer edge of the spray. The problem with this is it waste allot of paint and can lead to a rougher finish because the paint at the edges of the spray are heavier and the paint in the middle of the circle can dry in the air before it reaches the mini and then you will have all kinds of problems. The better nozzles are the line style. These spray a very thin oval that eliminates the dead spot in the middle of the round nozzles. The better ones even allow you to adjust the line for horizontal or vertical spraying.
