I sent a mail to coppercoat and, all the information I`ve been sent seemed enough to make my choice, as I may need a long last coat; because I am moving sardinha to cabo verde for the next two years.
We have just had coppercoat applied to our hull this year (The boat has only just been in the water for 2 weeks so cannot really give you an opinion yet)
The problem we had with it is the fact that asit is waterbased it has to be applied with no threat of rain. As you maybe aware we have had our fairshare of rain this summer.
We needed a whole dry day and we did not get that in June.
The process that was used was
apply the first coat and then wait 1.5hrs then apply the second coat then wait another 1.5hrs etc. They applied 5 coats so you see why we had to wait so long as the slightest water would wash all the copper off.
It goes on coppery brown and then goes green when its in the water.
We were told then that all the maintenance it should require is a wash of once a year. If there is growth then a slight rub down will expose a bit more copper and strenghten the resistance to growth. If however we find it does not work we can anti foul as normal.
The coppercoat was applied mixed in with the gel coat (we also had osmosis treatment) I dont know if this is different to applying it on top of the existing gel coat.
I will send some photos later
