First weathering using airbrush to dulcote

[AllenB]

Since I didn't have much luck with dulling from a spray can, I thought I'd try my luck with the airbrush. I thinned out the dulcote 50/50 with mineral spirits. I *THINK* the mineral spirits may have caused this whitish hazing. I'll try paint thinner next time. Thoughts???

are you using oil based paint or water based? It almost lookes like the clear coat was not mixed right or the brush still had some paint in it? Clear coat and whites are the most easly messed up from a dirty brush. This is why I like water based for weathering as its easy to clean you can thin it down so you will still see the detail behind the weathering paint. the other thing that could have happend is that the clear was drying to fast and the air brush was just splattering the dry and wet paint on the model. Dont feel bad we all have done it!!! as a seggestion. Test whites light colors and clears on a diffrent surface before its put on a model. this way you might catch a mistake before it ends up on the model.

Thanks Trent. I'm using simply Testors Dulcote and mineral spirits. When it first goes on it looks great. Then dries with that haze. I thought I had it mixed well. What do you use to dull/seal weathering powders?
Thanks!

I like to use polly scale water based paints then seal them with poly scale or Testors flat clear. If Im putting decales on or weathering powder I use gloss clear, add decals/powder, then gloss clear again to seal them in. then I will put flat or semi gloss on depending on the model and final finish I am going after

Allen, read your other thread about airbrushes. I think I answered your questions over there.

Testors Dullcote is a laquer. Thin it with only Testors Metalizer thinner or commercial grade laquer thinner as a second choice. Metalizer paints from Testors are laquers. Enamel thinners and mineral spirits won't work as you found out.

A 50 / 50 mix ratio is what I use with it and 15 psi at my air brush. Too much pressure will make the thinner evaporate too quick and the Dullcoat goes on dry.

You can also thin Dullcote with Xylene or Xylol from Home Depot, WalMart, etc. Lacquer thinner can be tricky when used on plastic. I use Xylene almost universally on solvent based paints, and have never found anything it does not like. I do use the Testors Metalizer thinner with their Metalizer paints though.
