tractor_37260 Posted April 4, 2019 Share Posted April 4, 2019 What's best to clean the airbrush out after using Johnson's original Klear ? Cellulose Thinners perhaps.... Suggestions welcome.... TIA Link to post Share on other sites More sharing options...
RMweb Gold Mick Bonwick Posted April 5, 2019 RMweb Gold Share Posted April 5, 2019 White spirit, IMMEDIATELY after finishing the application. It's a 'wax' polish! Cellulose thinners might do it, but I've never tried that. 1 1 Link to post Share on other sites More sharing options...
RMweb Premium mezzoman253 Posted April 5, 2019 RMweb Premium Share Posted April 5, 2019 Ammonia based products are best for thinning and cleaning Klear. As it's acrylic based I wouldn't use white spirit. See http://www.swannysmodels.com/TheCompleteFuture.html for a complete guide. Old but still relavent. The new version, milky white, does exactly the same job as the old clear version. There's lots of video's on line regarding it. HTH Rob 4 Link to post Share on other sites More sharing options...

RMweb Premium Barry O Posted April 5, 2019 RMweb Premium Share Posted April 5, 2019 If you are spraying it (Klear) just make sure it doesn't get on wheels and mechanisms. How do I know? spent hours polishing it off some wheels and pick ups while fitting a Zimo sound chip to an A1 pacific.. Klear is not a good conductor of electricity!

RMweb Gold 57xx Posted April 6, 2019 RMweb Gold Share Posted April 6, 2019 I've just used water with no problem. As long as you do it right after spraying and haven't let it dry out, it seems fine. Link to post Share on other sites More sharing options...
Kiwi Posted April 7, 2019 Share Posted April 7, 2019 I’m surprised to hear that anyone airbrushes klear. Its extremely viscous (assuming thats the right word for “runny” ) so hard to persuade brush marks to stay on it. I would expect airbrushing would cause more problems than it solves. I’ve used it on small parts by just holding with tweezers, dunk in bath of klear, hold up to drain excess, then leave on paper towel to dry under a dust proof cover. Leaves an amazing finish. A simple wash over with a brush also very easy to apply well. Link to post Share on other sites More sharing options...

The only 'problem' that I've seen mentioned here is avoiding contact with electrically conducting surfaces - which is common sense and hardly a problem. As I usually hand brush Klear, I am aware that it is perfectly possible to create runs if the brush is inadvertently slightly overloaded. Airbrushing Klear is no problem whatsoever.

I do plenty of airbrushing, but just don’t bother for this. There is no specific Klear related "problem" or "issue" in this thread. Spraying stuff on to wheels/pickups is just careless (sorry Baz!) and as much a problem for any paint or varnish being airbrushed. It's easy to clean off dried Klear using Windolene or any amonia based product, just as easy as removing enamel or acrylic paint. Cleaning an airbrush is not an "issue" either. I've brushed Klear and airbrushed it. With brushing I've found it's easy to flood fine detail because it so fluid. With an airbrush I have greater control of the amount applied. I'll use both techniques depending on the finish I'm after. Link to post Share on other sites More sharing options...
RMweb Premium Barry O Posted April 27, 2019 RMweb Premium Share Posted April 27, 2019 Yes it is careless. In the case in point it was a respected loco builder/painter. Problem is spotting the darn stuff! It is a warning to all who spray varnish onto their models...best to take the chassis out before spraying or just don't spray at all.
