hi fellas,i'm spar dashing tomoz & the scratch coat has been on for a few weeks so when i hose it down how long should i wait before applying the top coat or do you just hit it pretty much straight away?

Firstly give it a light spray and watch how the water is reacting , you dont want to soak it cause the top coat will slump when you dash it .

if there is water repellant in the scratch coat then dont wet it at all mate just do a small test bit to check for suction... good water repellant will hold the second coat for ages...
