Has anyone tried airbrushing the new Model Master Acryl semi-gloss black #FS27038. For about the past 5-6 years I have been airbrushing frames, floor pans, wheel wells, etc. with Model Master Acryl semi-gloss black #4700 with great looking results. When I start spraying this new formula it isn't long before it starts clogging up the spray tip and eventually I have to stop. When I recently ordered a couple of bottles of this product and it arrived with new labeling and product number and I didn't think anything about it. I thinned it the same as I always have and have not been able to get the same results I was getting in the past. I did find some vendors referring to a "new formulation" but nothing else about it. I have emailed Testors but have not received a reply yet, so I wonder if anyone else has experienced this problem.
