Excellent, many thanks.

(funny how the mind works - I've just remembered the first ever summary of the uses of Future in modelling that I read - it said that Future can be coloured with food dye!  and there's a supermarket on my way home from work!  Now why didn't I remember this two days ago?)

Tamiya acrylic clear, comes in quite a few shades. Thin with isopropyl alcohol for airbrushing, clean with Simple Green, Windex, or ammonia solution, followed by a water rinse.

Thanks that confirms it wasn't just me and/or something in my set-up.

Now the bonus question - can anyone suggest a suitable alternative for clear colour that does handle Future ok?

Thanks again,

K

Hi - I had the same problem with that color on a piece of untreated acrylic. It works fine on untreated polystyrene but chokes on acrylic for some reason. It will stay clear over a standard kit clear part but I wouldn't use it on vacform canopies ever again. It could be the future that causes the same reaction?

Okay, that clears it up. Something in that particular paint is not compatible with acrylics of any type.

Normally, Future plays well with enamels and lacquers provided the base coat is completely cured.

As you noted, Humbrol clear colors may not be the same composition as their opaque colors. They may contain a solvent that attacked the Future, or they may contain a binder-solvent combination that is incompatible with the Future, or the Future may not have completely cured.

Thanks Mike, I've not had problems with enamels/future before (after all usually frame lines on canopies are painted after a future coat is applied).

Also, not sure if the Humbrol clear colors are enamels - brushes need cleaning in cellulose cleaners which would suggest not.

Thanks

At a guess I would say it is actually the Future that has casued it to turn opaque. From memory Future is an acrylic based product and probably reacts badly with enamels. I am sure someone with more experience than myself will be able to confirm or deny this for you.

Advice/help - Humbrol clear color #1325
Posted by OhOh on Monday, October 2, 2006 4:12 AM

Any idea what would cause Humbrol #1325 (actually their clear color green) to dry opaque white?

It was stirred, not thinned, painted over a clear canopy protected with two coats of Future.  A new brush was used, it was left to dry under a plastic tub.  It's definitely the paint that has opaqued, it's not the canopy plastic.

 

Any suggestions on how to avoid it in the future AND more importantly how to clean up the canopy (which amounts to removing the Clear color without removing the future?

 

Thanks.
