Your Tornado is a Marstrom? Marstroms come from the factory painted with Spies Hecker auto paint. The cloest US equivilent is IMRON pure white base. A good auto paint shop can make up some 1 part touchup paint for you.

If you will do a search, you will find a thread on this from a couple of years ago.

I can't imagine anyone coating an expoxy boat with gelcoat. You would have to prime it to get it to stick
