I know this is the preferred method of applying two pack paint to boats,
My question is:

What is the most suitable two pack paint "type" to brush over freshly
primed and under coated "synthetic"?.

Can two pack be re-applied more than once over previous layers again
by using brush application? and I wish to avoid any likelihood of a
solvent reaction.

Can anyone please suggest a two pack paint available in the UK that will
perform exactly as described above?.

Steve.
