Stevepd Posted January 9, 2019 Share Posted January 9, 2019 (edited) I had time today to progress my Tornado. I almost always use Xtracrylix and up to now have never had any paint issues. However I sprayed the model DSG and brought it inside to go off (freezing in the garage). I came back to it a couple of hours later and saw this brown stain patching effect all over the model. Any ideas or habve you seen this before? Steve. Edited January 9, 2019 by Stevepd Link to comment Share on other sites More sharing options...
Out2gtcha Posted January 9, 2019 Share Posted January 9, 2019 That is odd. Not seen that before. Contaminated paint? Too cold/freezing > warm drying temps? Link to comment Share on other sites More sharing options...
Stevepd Posted January 9, 2019 Author Share Posted January 9, 2019 (edited) I’ve checked in the airbrush paint pot and there is no floating film. I’ve decanted it back into its pot, given it a rigorous shake and put it in the airing cupboard to warm it through. Steve.

Ryan Posted January 9, 2019 Share Posted January 9, 2019 Can you replicate the problem on a scrap model or card? I have never seen this phenomenon. Ryan Stevepd 1 Link to comment Share on other sites More sharing options...
Out2gtcha Posted January 9, 2019 Share Posted January 9, 2019 I may be inclined to use something VERY fine to strain the paint through after taking the AB completely apart and cleaning every square mm of it. On several different occasions I have seen weird stuff from dirty ABs. Not saying that is the cause, as the blemishes are strange indeed, but good to eliminate something like a dirty AB or contaminated paint. I might even try to shoot something completely different through it, to see if there is any change or blotching. Stevepd and Ryan 2 Link to comment Share on other sites More sharing options...
mhorina Posted January 9, 2019 Share Posted January 9, 2019 How do you power your AB ? Maybe something went wrong a/c outside temperature. Air tank to cold, compressor moisture? Link to comment Share on other sites More sharing options...
BiggTim Posted January 10, 2019 Share Posted January 10, 2019 I have seen things like this before, and it's usually a bad reaction with a substrate or contaminant on the surface. More common with flat paints than gloss, too. Did you prime first? Tim Link to comment Share on other sites More sharing options...
Stevepd Posted January 11, 2019 Author Share Posted January 11, 2019 I cleaned the airbrush as it hadn’t been used for some months prior to the Tornado. The paint was left in the airing cupboard and occasionally shakes. I’ve resprayed it this afternoon and it’s worked a treat. I suspect I did not shake the pot enough having sat around for a bit, so human error. Steve. BiggTim 1 Link to comment Share on other sites More sharing options...
