Good advise above ...
Use this primer >>>
Shepherd Marine - Shepherd Marine
Top coat there are loads of options but I am using this single pack acrylic >>>
Shepherd Marine - Pioner Topcoat easy to do futures coats , just clean , light rub down and recoat , part of the reason I have gone for that one ...
There is a low temp additive as well and all the thinners you need for spaying , make sure you use the right one .
Anti fouling is up to you , I am not bothering ...
As I said there are many options for both primer and top coats , all depends what you want or need to achieve .. Have a look on the web page , contact them , they are very helpful , do your research and most of all get the prep work right ...
Hope that helps
