OK, nearly had an epic fail today.
Earlier today I painted a strip of foamcore with some Wicked Black as a base for a coat of Mirror. Nothing fancy, just used a foam brush to paint the black paint onto the black paper of the foamcore strip.
After dinner I got a nice flat artist brush and the Mirror paint and started spreading some onto the black-painted surface. My brush was too wide to dip into the tiny bottle of Mirror, so I was preparing to pour just a drop out onto the foamcore. Well, I'm a klutz and I spilled a lot more than a drop out, onto the foamcore, the table, and spatters on the floor and my socks. Splatters came within an inch or two of my asteroid hunter!!
Deciding I could clean things later I quickly spread the precious fluid over the foamcore, but there was a puddle of it left over, on the table surface. Thinking quickly I grabbed the first BT50 elongated plastic nosecone I could find, straight out of the bulk cone bag, and began applying the Mirror. I didn't want to waste it, and I was planning to try it out on a cone anyway (after cleaning, lightly sanding, and priming the plastic cone). No time for that, just dipped brush in puddle and started covering the cone. I wound up over-working the material: I've found it will settle on its own if you just paint a super thin coat and don't overwork it. But I "scratched" the settling surface by overworking it. I set it aside vertically to dry, then cleaned up my mess.
This included using lacquer thinner on the brush to clean it, but after I was nearly done the brush snapped where the plastic handle met the metal band holding the bristles. Oh, yeah. Cheap brush, lacquer thinner, bad combo. Into the trash.
Anyway, here is a picture of the foamcore:
You can see the black paper to the left, a moderately shiny area that is simply the foamcore paper coated in Mirror, then a shinier area to the right where the Wicked Black undercoat sealed the paper surface before Mirror application. I will cut that shiny area into two halves, and for each half, I will coat half of it in a clearcoat, leaving the other half of the half untouched. The two clears will include Future (or whatever it's called now) and Krylon UV stable gloss clear. Since metalic silvery paints often self destruct visually when clear coated, this is an important test. I can do the Future tomorrow night but will have to wait for a paintable day to spray the Krylon outside.
Meanwhile check out the nose cone. The stuff settled a bit, despite my overworking it:
It definitely dries more mirrory (mirrorry?) than it looks when it is wet.
This piece will become part of "Through the Looking Glass" but I may buff the Mirror down and recoat, probably with an airbrush if I find it works in that application. I lost smoothness from overworking the material in my haste.
