Hello!

I recently decide to switch from vallejo primers to tamiya primer, the kind that you airbrush.

All turned out well although I might've underthinned a couple of batches.

After pieces sprayed with that batch dried I noticed that, aside from their texture being more rougher, if I rub them even slightly some primer will come off. I would say it looks and feel like powder. Just a minute amount, the pieces are still fine I think.

Is this normal? Can I still spray over it with my base coat? Should I reprime? Can I just wipe the powder off?

Thanks any help would be appreciated.

PS. would be good to note that other batches, the ones I thinned correctly, are smooth and are near perfect
