I personally have no issues with the urethane dash, They can be trimmed to fit and will last much longer than what vinyl skinnned. IMO it is perfect for a Driver.
With that said...
1) Clean with lacquer thinner
2)wash with soapy water, rinse and rewash . Note: adding ammonia to this will help clean older parts
3) thoroughly dry the parts, it helps to dry with an air nozzle
I use paint from the auto paint store, but you can use Cans I used SEM
4) prep the surface with vinyl prep
5) paint the surface with light, even overlapping coats, dont try to paint them fully covered in 1 session.
