McG Posted November 18, 2020 Share Posted November 18, 2020 Every time I spray Tamiya XF-18 I get occasional blobs that appear in the finished paint. The paint is roughly mixed 2/3 paint to 1/3 XF-20A, and we'll shaken then stirred before use. I've also added a couple of drops of Vallejo flow improver to stop clogging. Any ideas what is causing this? Do I need to add more thinner? Link to comment Share on other sites More sharing options...
Steve Noble Posted November 18, 2020 Share Posted November 18, 2020 I usually mix 50:50 equal paint to thinner as a starting point, then check how it sprays. I'll add more thinner if it's not spraying well enough. Link to comment Share on other sites More sharing options...

McG Posted November 19, 2020 Author Share Posted November 19, 2020 Thanks to Steve's tip to add more thinner, I have been able to get nice smooth applications of the paint. Just letting it fully dry over night now. 1 Link to comment Share on other sites More sharing options...
dogsbody Posted November 19, 2020 Share Posted November 19, 2020 I have only used my airbrush once and have only used Tamiya XF-16 Flat Aluminum. I thinned it about 45 to 65, paint to X20A thinner, with maybe another couple percent of Tamiya Paint Retarder. I sprayed it through a Badger 150 IL, at 12 to 15 psi. Here it is on my paint mule. And on my 1/72 Hurricane. I didn't have any splatters or tip drying issues. I haven't sprayed any other Tamiya paint yet, so I can't make any recommendations other than to thin the paint out a bit more. Chris 1 Link to comment Share on other sites More sharing options...
