It's just honest reporting. When I do kit reviews, I want to describe exactly what the hobbyist will find when he or she opens the box and pulls out the parts. That's all it is. "For the record, this is what I found." I've received kits with paper thin flash, or no flash, like nearly every...

If you're using acrylic paint, thin with Transparent Airbrush Extender. This will effectively turn the paint into a sprayable filter. Make it as light as possible and give that a shot. You might want to seal with a clear lacquer first so if the effect isn't what you're looking for, you can clean it ...

An enamel primer, like Testors Model Master Car Enamel Primer might level out better than any other type of primer, but you don't really get close to the even thin coating that spraying will yield, and then there's the smell of enamel paint and paint thinner to deal with. I bought me a Dayton exhaus...

No. A hair dryer won't be hot enough or even enough to give you a good cure. Huh. I use the oven all the time. Many of the crafty polymer sculpting ladies I've met use their ovens for curing their crafty polymer jewelry use their ovens too. I think this stuff was designed for that, no?

After baking, leave the sculpt in the oven to cool down really slowly. Otherwise, the polymer clay has a tendancy to crack. Sculpey sets really well at about 250 degrees or higher.

Try giving it a coat of epoxy putty instead. Squadron green shrinks a lot, and softens the styrene underneath. It's also fairly brittle, so if there's even a bit of flexing between your styrene planking, it'll crack. I would coarse sand the form, to give the epoxy some tooth, then apply the putty, a...

You could sand down some of the epoxy at the tip of the LED, I think that helps spread the light out better. You could also buy some of these 360 degree LEDs from superbrightleds.com. I got a few to put into some starship engines and they really do cast light in all directions.

They have a range of very bright white LEDs with various viewing angles from 15 degress to 360 degrees.

A new one from them is a "warm white" led. It's only available at 35 degress, but it might be interesting to try them out with the blueish white LEDs.

Be careful handling the surface, as the Metalizers are quite fragile. They really do need to be sealed after airbrushing. I like SnJ Metallizing finish.

Reflectivity aside, silver paint seems to be more opaque than any other paint. I've done some test a couple of years back and almost all other paint colors have some level of light bleed. The metallics were either opaque or nearly opaque--at least to the point where I couldn't discern any light bleed.

Kind of. But if the jaws that hold the blade in are hollow rather than solid, I think your drill bit will not be secure enough to be useful, the thinner ones are quite fragile and any uneveness in pressure will shear the bit. Most pin vises go for under $10.

Depending on the paint, it can take a couple of minutes to a couple of hours. Progressively check on the parts. I'd start with a couple of hours. See if the paint is lifting off. If not, leave it in the solution overnight. Check the next day.
