Model kits make great gifts - no matter if you are young or old !








Primer helps prep a model part for paint. If you've done any sanding on the model, or any putty work, you'll have high and low spots, and an uneven texture.

Shooting the model part with primer allows you to sand the model with fine sand paper to get a smooth finish layer to shoot paint on.

If you can see an imperfection in the model part covered with primer - you will notice it even more whan you cover it with paint.

Some primers can even act as a filler for minor imperfections.

Fine primer is especially designed for models, which are often a very smale scale when compared to painting a real car or a piece of furniture.

If you use automotive paints, primer is usually required. Automotive paints (or almost any paint not designed specifically for models) can etch the plastic, sometimes even melt it. You need the primer to help act as a barrier.

Primer can also be useful for models that are molded in color. Shooting a black molded model with white or gray primer can help with painting the model a lighter color than what it was molded in.

Red Oxide primer is good for paint colors like red or orange, or yellow.

Black primer is good for dark colors, including black.

White is almost good for any paint color, especially if you want to lighten your paint color up some (for instance, when the model is molded in a grey color as many are).

Pink primer is used on figures as a base coat, or if you want to paint a model red. (Ferrari for instance uses a pink primer on some of their cars).

Most modelers have their favorite primer. Once they find one they like they tend to stick with it for years.

Model puttys vary in the way they are made. White putty is most common, though some are "red" (more of an orange color) and some are green.

Some puttys, like the Squadron Green, has model glue mixed into it, and it helps bond to plastic by sometimes melting it some.

Again, modelers have their favorite puttys they tend to use for years, so it's a matter of preference.

On many models there are seams to fill, modifications to make, and scratchbuilt parts to fabricate and attach.

Many of these will require some body work and filler of some kind.

Here we have various primer and putty choices.

Most of these primers are specifically made for modeling. But there are times when you are building models from metal, resin, vinyl, or other materials that are not the standard plastic in a kit.

In cases like these I personally use an automotive primer. These kinds of primers will stick and adhere to almost anything - any material. It's extremely rare, if ever, that I have had an issue where the automotive primer did not stick.

Currently I use 2N1 Grey Primer (if using a can). It has a very important fan spray nozzle that allows you to lay down thin coats.

My personal choice for putty at this time is Tamiya White Putty.
