Light Blocking Colors

I've been using Dupilcolor's Bumper Coating Material out of the rattle can as a light blocking/bleed coating, but It seems as if they've changed its pigment density so it now is no different than black spray paint. What are other choices for a light blocking coat? Since in a few cases it will need to go entirely on the exterior of the model, I'm looking for something that will completely block out all light bleed/leaks with only a few thin coats.

An out of the bottle color for plugging up pinhole leaks I will need also.

On my cricket phaser the whole emitter (black section) is clear red resin. It has a 3,000mcd 5mm LED in it. It needed serious light blocking! I used Duplicolor grey primer followed by Krylon flat black. Check out the video. It worked pretty good.

Chrome-Spray-Rattlecans or any other "metall"-paint wil work well. Such as Tamiya Silver for example.

Silver-paints will block even better than black paints because of their pigments.

Heared that from another forum-menber over at phoxim.de, tried it and found out he was right.

Now I use chrome silver in rattlecan. Pretty cheap and acrylics also. So no problems with compatibilites..

Give it a try...

I've recently started using Montana Gold rattle cans on my acrylic back-lit displays. I had been using Krylon Fusion, but it was taking several coats to make it completely opaque. Two coats of the Montana Gold black and I can hold it inches from a super-bright desktop light and nothing gets through! It also goes on with very little overspray and dries pretty much in minutes.

That said, I picked up a can of Montana's silver and tried it out on one of the saucer halves of a 1/350 Enterprise. Same qualities...only better! The paint isn't cheap, something like $8 a can, but it goes a lot further than other rattle cans.

Where can you find this brand?

I found it at Dick Blick's, I think a lot of other artist supply stores carry it as well. It's intended to be used as graffiti paint.
