I loved the Grafspeed in the bottom of my mirror back in the 60s. As Sam says, the big advantage was that is was easy to sand very smooth - and unbelievably messy to do.
But it was also great at absorbing the rays when it was sunny. I made the mistake of leaving it upside down for a week one summer and when I came back it had blistered up all over.

Me Never found it as easy to sand flat as they claimed and found it cracked on my Mirror until the bottom looked like crazy paving. Cute Mr Sheen story |

There's Durepox and there's Durepox. The Moths have been using Durepox primer for foil finishing since forever - you've got a nice few days window from spraying to flatten back to a smooth finish before it goes really hard.
The Durepox topcoat I think has PTFE in it if I remember rightly. Also goes pretty hard and I'd probably use it over a 2 pack polyurethane or 2k car paint. Done a couple of boats with it and it's nice enough.

This stuff is pretty new, so I've probably got the name wrong, whatever it is they are interested enough to ask for stickers for the speed record attempt, I'll try and find out more, might see him at an event tomorrow. |

OK, so I have an update, this is a new Durepox Extreme version even tougher and slippyer, will report more news when I have it, have also come across an incredible new foam that withstands amazing loads yet is almost as light as EPS it's being used by a new Surfboard manufacturer called Appletree who's boards we now rep over here. Interesting the march of development still continues. Lots of exciting development coming out of Portugal of all places thanks to massive EU investment.

It appears GRF's go-fast bubbles finally may be a go-er:
“Carpets of bubbles” will soon save shipping giant MSC £220m in fuel costs after it signed up to put a British company’s revolutionary technology on a fleet of new cargo ships. MSC will install Silverstream Technologies’ “air lubrication” design on 30 container ships it has ordered from southeast Asian shipyards." https://www.telegraph.co.uk/business/2021/09/22/carpets-bubbles-slash-fuel-costs-container-ships/ |
