[400TT]

Yes, Buff with Gelcoat(boat) polish. If you make it smooth it will not mark as easy and be easier to clean off if you do mark it.

If you want to leave it in gelcoat long term:

* You will also need to file/sand the seams

* Paint the bonnet/boot/door edges.

* Then throw some stickers on.

My brothers black Harrison is still in Gelcoat. And like David says, you can't tell if you stand a few metres away.
