Repainting 60hp Tohatsu Engine Cowl

I'm about to attempt to repair a Tohatsu engine cowl that received a couple of dings. I'm pretty sure this can be repaired from the inside with fibreglass, and the outside with plastic padding and then sanded smooth. I've already purchased genuine Tohatsu decals as I want a completely professional job.

The final top coat (black) will be done by an autobody repair shop, however I have to get it to the pre-top coat stage. Do I have to use a special primer undercoat particular for engine cowls?

Not really an issue, your bodyshop guys will get it right. A plastic primer is required on plastic but not GRP. Presumably they'll use a basecoat a lacquer system which will look as good as new.

Thanks for that. Personally I could do without the hassle of repairing it, but the engine is mint, so it'll be worth the trouble of getting it done. I'm assuming the body shop can oven-bake it too, so the top coat is nice and tough.
