primer color?

i was just wondering if anyone has tried using Tamiya White Primer as the color of their car, and then just clearcoating over it to give it a shine.

im asking this because i sorta like the white from the primer more than TS26 (Pure White) and so i wanna try doing that for one of my cars.

Never heard of it being done before....seems alot of extra work though.

Pretty hard to beat the shine of TS-26 Pure white.

I have already make this with Duplicolor Black primer.. result was quite aceptable.. but if you look very close, you can see grain under the clear.

I have never heard of doing that b4 now...seems to work ok...
