[snip]

I didnt thin the first coat of primer/undercoat but too late now.
But have gone for thin application coats.


After applying the initial primer coat/s it is customary to
then build up with undercoat which can be flatted back without
fear of losing protection, then apply two gloss coats.

You can apply several undercoat layers if required as it is the
undercoat finish you work in order to achieve the better finish.
