Peak C-5 Has Problems Shooting Testors Metallics...

I'd try a couple of things. I'd suggest buying some new paint. Perhaps buy one jar and try it out on a scrap model. I suspect the age of the paint, especially metallic, has a lot to do with your issue. Also, those metalizers shouldn't need thinned so again probably the age of the paints is the main issue. Also make sure you have a vapor trap attached to your airbrush hose. If there's a lot of humidity where you live that can cause issues too. I've not had much success with MM Metalizers. I prefer Alclad as they are quick drying easier to apply and very easy to mask. The metalizers can be difficult to mask if your planning on doing multipule panels as the paint will tend to peel off when you remove the tape. Although Testors has a Metalizer sealer that you're supposed to use with it too. Other folks may have had better success.

I hope this helps.

Here's a model I did using the Alclad NMF

P.S. I love you're avitar!

Most airbrushes have trouble with paints with metallizers, expecially ones with fine needles. The paint is just too chunky to shoot! And especially with older paints that are thickening up. You could try adding thinner, but you might be better off with new paint.

I think you bring up an important point about high-precision airbrushes not handling metallics well. We want the most precice spray patterns possible but this may come at a cost as seen in the example with the metallics. I think the smart solution is to get that old-fashioned Paasche VL airbrush which comes with 3 needle sizes.

Or the 100/200 series from Badger that comes with Fine, Medium and Coarse needles. I use the medium needle 95% of the time and occasionally pull out my spare 100LG that has the fine needle installed. I have the coarse assembly as well, but haven't had any problems spraying Tamiya Metallics with the medium needle, so it's never been used.
