re-spray?

[greg1.4]

hi, i am going to be spraying my nova soon.. using 2k.

i am going to buy 3 litres of black 2k, 2k hardener, 2k thinners but i need to know how much to mix etc. is there a ratio etc?

i have only used polyeurothane paint when spraying before.

also do i put a laquer over the top of the paint when it dries?

i want a really nice shiny finish, any tips for getting that too?

cheers
Greg
