Hi,

So I've finished my Fieldhockey keeper Helmet...
No clearcoat was used.
I've used resin infusion but had some trouble with the vac bag and had a tiny little hole in it. it lost some vacuum after 8h I think...
Ive used the IN2 epoxy SLOW hardener...

So I would like to get a finnishing coat on it, what doe you think the best way is?

-Spraygunning clear epoxy on it
-Brush epoxy on it and let the excess epoxy drip of the part
-Spraygunning a topcoat (should have to buy it...so prefere the first option

Fill them with some resin. Will be tedious but necessary if you want to be able to just simply spray over.

You could try wiping resin on then off again so you only use a thin layer to fill the pinholes.  Or just paint on another few thin layers of resin like you would do with carbon skinning.

You would of course need to sand it smooth again afterwards.
