I just finished this for a friend of mine, and I was kinda pleased with the results. So I thought I would share it with the group.
So what we started with was a very pitted and flaky Bride of Pinbot helmet assembly. Here is the before shot. As you can tell, the finish has come off it in several places. My goal is to put a new silver-chrome finish on it.
So first off I will talk a little bit about the paint system I will be using. It is call Alclad, and was developed for use on scale models. I have used it many times over the years, and the stuff is great. Here is a P-51c I did years ago that is now the gate guardian to my work bench.
This Alclad comes in many shades of silver that can be used for the paneling effects on model aircraft. For this job I chose the Chrome color.
Alclad is a very hot laquer, and can only be applied with an airbrush. I have a Paasche dual action airbrush that I use in scale modeling, and sometimes to touch up playfields. The paint comes in small 1 oz bottles, and cost about $9 per bottle. It can be purchased as better hobby shops, and on Amazon.
So I started off removing the old finish. It came off very easily with 800 grit wet-dry sand paper. You want to get the surface as smooth as possible before putting on the base coat.
All Alclad finishes require a base coat. For Chrome, the suggested base coat is an oil based enamel gloss black. Alclad sells a quality gloss black that you can usually pick up a the hobby shop when you get paint.
Spraying gloss enamel is tricky. If you spray with too much pressure, or are too far away from the model when you spray, it will flash before it gets to the subject, and look dull. To get a good coat, you have to put it on thick and wet. One way to get around this problem is to sand and polish the base coat before you put on the chrome top coat.
So here is the helmet after the first base coat.
