So I’m over using Vallejo’s grey primer, it goes on really wet and the finish isn’t great in my opinion. I have some mr surfacer 1200, I’m curious if I can use it as a primer, I haven’t used it before (I have the thinner to compliment it too) my concern is i work in 1:160 scale (n scale) will I lose detail at all such as brickwork or would I be ok using it as a primer.

Appreciate any insight on this
