Should have said that I sprayed Vallejo acrylic Model Air light blue over the primers.

Thanks John,that about covers everything I need to know. If you can get Model Air to stick to the Badger and AK primers, then we don’t need to worry about sanding anymore.
I will just use up my Vallejo primer in non-sanding roles,or in places where they can be a color coat, just like paint.
Most of my painting for about the next decade or so is going to be Aeromaster or Polly Scale over AK or Badger primers,the little bit of LifeColor and Vallejo/Italeri I will use, I will just treat with kid gloves until I can get some AquaGloss or Aeromaster Clear sprayed over them. Hand brush Acrylic painters know that Polly and Aero can be brush painted onto parts that won’t be masked without a primer at all.

ps, one small thing for me to check on is to see if the Vallejo primers paint and adhere okay over the AK and Badger primers
Rex;
I was wondering that too as I don’t want to use a black primer under a light RLM color although it did fine in my test. I was thinking of the Vallejo grey/white on top of the black. I will give that test a run through this weekend.
I am working on Airfix’s 1/72 Fw-190 A/8, and I sprayed RLM02 in the wheel wells and RLM66 on the cockpit interior section over the bare plastic. All I did was wash the plastic, and the Vallejo Model Air did not lift when I tried to using the Scotch Blue tape. I think the key is to wait 24 hours for the paint to cure (even though it seem dry on just a few hours) and make sure the plastic is prepped properly.

I decided to push things a little and see what I could get. I sprayed the Badger black over a large section on the card. After 6 hours, I detected no odor and decided to spray the Vallejo over it in three different patterns. Fine mist to lighten it, almost total coverage in multiple passes, and blast a full on heavy coat on. I separated each section with a piece of Tamiya tape. I then waited 6 more hours and did my tape test just with Tamiya. See below the result with the misting on the left and the blast on the right.
Some came up. It is interesting to note that what pulled up was the black from under the tape and then I was able with additional taping and pulling to spread the area that came up. Now this is after only 12 hours instead of 48. I will try after 24 and see if I can continue to pull it up. Interesting that it only came up in one area and the others were solid when I tried to pull it off.
The imperfection on the right is some lint that got on the card when I was blasting. It is not from the primer.
