Hey my posting was a polite reply just saying it's better then AF, even if it's not working how you would like it To do
What is it with you , you seen to want to be bite my head off when ever I reply to one of your posting .
Carry on like that and I won't bother again .

No intention to" bite your head off". Why would you think that? Nothing in my post was meant to be derogatory. If it was then I would apologise.

I have no animosity to anything that you say. You are always entitled to an opinion in the same way that I am entitled to mine. I do not always read the name of the person I am replying to so cannot recall when I last commented to one of your posts. Hence, I have no idea if we agreed then, or not. From what you suggest it was "not". Does it matter? Not in the least.

Whether you post, or not, is your decision. But if you opt out because you do not like what another says, really only makes you the loser. So I suggest that you do "bother", because I am sure many like to read your views on all matters - even if they do not always match those of fellow forumites.

Rollers? Anyone have an amazon/ebay link for the rollers they used to apply coppercoat?

Rollers are a nightmare with epoxy or any other viscous coating. Round shoulders and solvent resistant, if you find a source of good ones, shout it from the rooftop. I get mine from a trade supplies guy, they’re okay but not good enough to recommend. They break up after a while, you have to spot that coming, or you’ll be picking its of foam off the coppercoat.

Rollers you be just as well to get them from CC .

He one cc that was done professionally serval time and they still couldn't get it right .

Got given a few from the boat painters company where I got the coppercoat, brand name Riga. They must get through hundreds of rollers. Not found them online yet.

Istr coppercoating a boat the coppercoat epoxy was loads easier to work with than normal epoxy. And can washed in water.

AMC supplied mine; they worked fine. But I didn't see any brand marks on them.

I made a mistake when my keel was sand blasted. I did not realise that the primer paint supplied by CC would do several coats & I mixed it all in one go. So although the keel was coated very thickly within 20 mins of blasting it did not have enough primer. Hence after a few years the rust began to come through. This started at the hull joint so was unavoidable really.
The result was that I had to apply another coat to the keel. It was very hot weather & I had to add the max amount of thinners ( from memory circa 5%) to get it to roll on rather than stay stuck to the roller. The resulting finish was much, much smoother & shiny surface, than the hull . The hull being more like a micro golf ball prior to sanding. ( but a very fine golf ball)
When the boat was lifted in St Helier the keel was very clean. The hull was very bad all over.
Since then I have had to touch up some spots on the the keel, 3 times & have since antifouled it as has finally given up the ghost, like the hull.
If I end up doing the next application myself I will use the maxm amount of thinners on the last 2 coats to see if it gives me a smoother finish. I note in the video that is shown in the above quote that the first set of patches worked better & were smoother. I am beginning to suspect that the amount of thinners has a bearing on the smoothness of the final coat & this how well it resists foulling. Perhaps the film of slime & subsequent growth attaches itself into the micro indents in the surface. An erodable antifoul paint has these indents but they collapse in the erosion process, unlike the much slower erosion process of CC

We hauled out yesterday, 16 months from last scrub and all that time in warmer waters. The photo is just as she came out and before any washing off. No barnacles apart from on the fridge cooler plate, SSB ground plate and a few between rudder and skeg. Just a thin layer of slime on the hull which washed off easily and a very thin layer of fouling at the waterline.

Very happy with that!
