Pedros, Galmpton. What's the latest? Awlgrip/Coppercoat

I often seem to read that the effectiveness of a coppercoat finish depends on how well it is applied. So I would be even more picky than usual in choosing someone for this job.

Peter: surely no-one knows that. All one can properly deduce from the many threads on the subject is that sometimes Coppercoat is, sometimes rather inexplicably, less effective than expected. To extrapolate that something about the quality of application is the cause of this variance may be natural, it may even be right, but I'd suggest it is not supported by any evidence.

Once it's on the hull there's not much to go wrong: the copper is there in the resin, right where it's supposed be. The exception to that is if the mix wasn't continuously stirred during application, in which case much of it tends to sink to the bottom of the pot and never gets near the boat. That's neither highly technical, nor does it require any skill to avoid. In fact the only compelling reason I know of to call in the professionals is that usually they will spray the stuff on, which gives a somewhat smoother finish.

Most other variables in application: temperature, humidity, etc will affect the 'best' applicators to precisely the same degree. Indeed, unless the pro has a climate-controlled shed, the amateur is arguably better placed: up to a point he can Coppercoat when he feels like it rather than being constrained by getting the job 'out the door'.

Sometimes the cured Coppercoat will need a burnish (scouring pad or 600 wet and dry) to expose the metallic copper. Sometimes, according to the odd disappointed poster, even that doesn't work. Why that should be, I don't know. Nor, I suspect, does anyone else.

The pro does have a climate controlled spray bay, otherwise I'd suggest he is not a pro paint shop, merely a general shipwright who sometimes dabbles in paint.

The company we used said that under no circumstances would they apply coppercoat outside in the yard.

I've had both Awlgrip and Coppercoat done at Pedros.

The Awlgrip (3 years ago) was a perfect job, done on time and to the agreed price.

The Coppercoat (a year later) has passed through everything from sub Antarctic to tropical waters and I have found it excellent.

Any weed growth is limited to slime which I doubt slows you much
Small barnacles are more troublesome but there again they taught Araldite how to do it.

The severest test was from S America to the Azores through tropical waters where growth flourishes. On hauling in the Azores there was no weed growth at all.

I know this is hotly debated, and there will always be exceptions, but a professional application greatly increases your chances of this stuff working.

Very happy with both jobs, done by Pedros
 
Thanks Paul. Very reassuring.

I had a very, very nice Awlgrip job done at Mylor some years ago. Sadly it is rather soft and tends to get rubbed by fenders, etc, quite easily.

I understand there are two types: Awlgrip Poly (G Line?) which is the harder wearing and Awlgrip Acrylic (2000?) which is softer but easier to repair/overcoat.

How is the Awlgrip holding up, Old Varnish? Can you recall which finish was used? I have a vested interest as I will probably have to go for another respray or re-gelcoat at some stage.

Didn't know there were two types. Whichever I had still looks like the day she came out of the shed, which is now three years ago. Certainly no signs of softness. And she's been in one or two rough places.
