Re: Bottom paint on prop

So just an update on the cost of Propspeed in New Zealand.

I have just have my boat out for its bi-annual birthday and went the Propseed route on the underwater gear.

I prepped the prop with a 320 grit flexible polishing pad on a small hand grinder, polished it till it gleamed, took me about 20 minutes. Then I used 200 grit water paper on the shaft, leaving the old acorn anode in place.

The Propspeed applicator guy came along, checked my work and was obviously satisfied, removed the anode, buffed the part of the shaft under the anode and masked it off. Then he washed the whole thing down with a Propspeed product (like thinners), applied a yellow primer in two coats and finally a clear top coat. The whole process took him about 45 minutes (not counting time between coats).

Total cost to me including local sales tax was NZ$127.50 so about US$100. That includes labour and cleaning materials, the products themselves.

For that kind of money, if it last two years as it has generally come to expected to, it's worth every cent (at least it is to me).

Yes, I always comment that manual labour must be just another Portuguese immigrant.

Regrettably some suppliers have an expectation that money should change hands when labour is offered.

Oh, apologies, you probably call it labor. The English folks have got it wrong again .

It is indeed interesting that the Merriam Webster dictionary says that "labour" is the English variant of "labor". Surely "labor" is the American variant of the English word "labour".

Actually it is probably some kind of up under slang english of some sort shape or form! Or in reality, probably as you note, more american than english, as England and Canada seem to speel it "labour" more than "labor"

BUT, if we can not have a bit o phun with funky speelings of words, what phun can we have?!?!?!?!

I wanted to throw an update on this product...

I sprayed the two coats on before launch this year and just had the opportunity to give it a look while swimming last weekend. I had to scrape the prop because it was completely covered with barnacles...this stuff wasn't worth the time it took to spray nevermind the $20 or so this grey primer (obviously that is all it is) cost me.

I may just bottom paint like all my friends next year

Re: Bottom paint on prop

Paul: I used some of this beautiful weather and your warm BC waters to snorkel under my boat more than once in the last week.

Our method of apply nothing to the prop and use the boat once a week or more often is working well. No barnacles on the prop or anywhere else.

Our bottom paint (Micron 66 I think, the salt water only stuff) is working well after 6 months too, but I'd expect nothing less.

I'm no longer participating on SailNet.

Don't know where you're located but this year on the Chesapeake, the barnacle issue is extreme, nothing is working short of using your boat often.

For several years I've used the Pettit Zinc Coat with great results, I can post pictures to prove it, but this year for whatever reason nothing seems to working around here.

Wingnwing should post a pic of what a diver scrapped from their boat docked in Annapolis, it was unbelievable. I have been trying to find a report that might explain, the only thing I have seen is refering to the bays health, which BTW is reported to have improved last year to a grade of "C" or "C-"

Re: Bottom paint on prop

Good to hear Alex, my technique was also "do nothing and just use the boat as often as possible". I put on some Pettit ablative on the bottom (I'm thinking it was Horizons?) so will see how that goes.
