When using spray paints, use a respirator mask. When sanding resin models, always use dust mask. All fine dust is hazardous.
PRIMING THE MODELS
Always wash any resin model before priming. A fingernail brush and Dawn detergent work well.
Use an automotive primer because hobby primers are not designed for resin. We strongly recommend Krylon brand Sandable Primers. Auto primers can be purchased at most hardware, automotive stores, Walmart and Kmart. Krylon primers come in gray, ruddy brown (dark red), white, and black.
First spray a couple of very light mist coats (let these coats dry completely before the next coat). This starts the bonding process. The spray final prime coat(s). Don't hurry and do not drown the model with primer. Spray several coats letting it dry between coats.
If you are in a hurry, spray the model, let the fumes clear, then dry with a hair dryer. Do this in a well ventilated area. Do not get the model too hot!
Some items might have air bubbles. On many items, bubbles can be made into bullet holes in walls and buildings. Just open the bubble with a hobby knife making the hole "cone" shaped. You might want to fill the holes on some models. There are many ways to fill bubbles: 5 minute epoxy, superglue or one of many hobby/model putties. I have used Elmer's brand Carpenters Interior Wood Filler.
Drybrushing is just that, painting with a dry brush. Dip in paint, wipe off the paint. Stroke the brush on napkin or paper towel, when no paint shows the brush is ready to use. Brushing across the model, the idea is to catch the tips of detail to highlight it. Use a lighter shade of the base color for drybrushing.
A large flat brush 1" wide drastically speeds up drybrushing.
A great product is Pelikan Ink: No. 15 Sepia. It is a brown / black color that is perfect for oil stains, rust and giving that aged or weathered look to any model.
