Personally, I would stay with just one system of paint.. The K36 primer is a high build primer and, as has been mentioned is very easy to work with.
I tip that I learned from an article written by Bill Harris.. (A master painter)
For the first coat of primer applied to a glassed surface..
Mix up some primer, thin it a bit, and then add micro balloon filler. Spoon it in ratio of about 50% primer to 50% micro balloons. You want the mix to be a nice thick paste consistency.
Now BRUSH this on to the finished wings. Apply nice and thick.
After cure, sand it ALL off except what remains in the low spots. It sands really easy.
This acts as a very light weight weave/ding/depression filler. You can then spray prime as normal, and won’t have anywhere near as many imperfections to work on..
