Question on paint primers

[Simpo Two]

I'm building a wooden model boat for display (think museum quality). The hull is going to be finished in satin white.

Currently it's had three coats of Halfords grey primer, rubbed down between each coat, and is almost ready for the top coat. However I'm not sure whether to go from the current battleship grey straight to the white top coat, or whether it would be better to apply a coat of white primer first. Any thoughts please?

White undercoat I would have thought before your topcoat.

Surely it depends on how many coats of top coats of white you apply.
Three years ago I made a bass guitar, I used rattle can white over a grey primer, it's still brilliant white now.

I'm using automotive aerosols; there doesn't seem to be 'undercoat' in that sphere.

Thanks. I'm sure it's doable that way but just wondered if a white primer would give a better finish. But then I read somewhere that if the primer is the same colour you can't see where the topcoat spray goes so well. Hmm....

I would suggest more coats of top coat. The top coat is going to give the better finish and contain more resistant colour.

Yep, after thinking about it that's the best I agree.

Paint arriving tomorrow!
