Great info. Thanks!
What is a good Primer?
You're welcome. If something helps, that's great!
My new primer of choice is Stynlyrez by Badger. A online friend here sent me a bottle last year, I've used nothing else since.
Other primers I've used and like (end echoing others above); Tamiya surface primer (all textures), Mr Surfacer, Alclad surface primer.
Two to run from (IMO). Model Master grey primer. Not even a primer, it is a color called grey primer. And Vallejo surface primer, which must be great for figure painting and stuff. But for the rest of us, it doesn't adhere that great and it doesn't sand, just gums up.
BTW, Vallejo acrylics (Model Air and Model Color) are my go to paints, so I'm not throwing stones at Vallejo, I just don't care for thier primer.
To chime in on the Tamiya discussion, I agree with my mates here, it is really good stuff and sprays great. But the color selection is way to limited for me, and I don't care to mix colors (just personal preference/laziness.....I actually admire folk who do custom mix)
