was down at HP before Christmas and bumped into a chap with a Sea Saga 27, started chatting and I happened to mention my task for the next couple of hours was to polish up my prop, he then waxed lyrical about some product he had used, couldn't recall the name of it but they sold it at Force 4, and he showed me his boat. His prop was like new, shiny and lovely and his boat had just come out the water after a full season use and it had just been jetted off by the yard and the prop had not been cleaned at all. One look at his prop got me wanting some of this stuff he had used. As I said he couldn't recall the name... but is was around £18 and he thought it might do 4 seasons...and it was simple clear stuff that you just wipe on and leave...and it was not prop-shield ( I used that last year, bit of a pig to warm up and apply and messy and TBH prop was only in marginally better nick this year.. )

I didn't go and check there and then at F4, but just had a look at their website and have drawn a blank... anyone know what it might be? I am hoping it wasn't Snake oil..

Just thought as I am going to LIBS next wednesday I would look it for it...

any ideas anyone? Obviously next time I am at HP I will try and track him down and ask..
 
be interested in seeing what this is, my props are in a hell of a state. i have some cleaning stuff which is supposed to bring them up well but be interested in a way of preventing for next season!

Howard, honestly this chaps prop came out gleaming! I think he said his boat's top speed was around 20knots and he said he cruises at 12 to 14knts. At 60+knots whatever the product he used may not stay on your props! But if it does it will be brilliant.

My prop was just covered with a coat of limescale, no other nasties on it so not horrendous.

I will find out what it is, even if I have to leave a message on his boat!

Oh, and Happy New Year :)

Happy new year James! We should be out of the water this time next week somewhere near you. Will try and catch up for a pint at the Ketch!
 
I've just ordered some Propshield and some Lanoguard - different approach this year.

We get good cheap lifts and scrubs in our yard.
They also have a really good powerful pressure washer.

Previously, we have coated the props with an antifoul. Some have used Propspeed. But with no great effect.
The props create too much of a disturbance for any coating to stay on.
After just a few weeks, antifoul coatings leave a rough "orange peel" effect which actually makes the prop less effecient.

So, my theory is to apply a coating that makes it easier to clean during our cheap lifts. The plan is to polish the prop back to new, then lightly abrade is and then follow Propshields process as detailed in this link.
http://www.propshield-industrial.com/application.htm
Note that I've selected Propshield Industrial, not the stuff you get in the chandlers. Apparently, the Industrial product is less solid and easier to apply.

I have also bought some standard lanolin in the form of Lanoguard. You can get Lanoguard from most chandlers - see here http://marinestore.co.uk/DA5055-600.html. Propshield is roughly 4 times the price of Lanoguard. Assuming that it has the same properties, I thought I'd treat the props differently - one with Propshield and the other with Lanoguard - applied in a similar way. Then at the end of the season we would know if it is worth paying the extra for Propshield.

I know that neither Lanoguard nor Propshield will stay on for the whole season but I am hoping that after a quick scrub, we will have nice shiny props each time we go off cruising.

We are off to do the annual maintenance in mid Feb. I'll keep you all posted.

We are also going to treat the hull to Coppercoat so lots happening on JW's underside this year.

he applied it himself and cost was £18 for bottle, so I don't think so, got to say it looks like it does a similar job to it though

... in fact just done a search and found this old thread... so can confirm it was not prop speed;

I did see that, that was the only thing I thought it might be, however the chap said he wiped it on... but perhaps I misheard... I am now popping down on Saturday to Hamble point so you never know, if he's there I will let you all know if this is the stuff.
 
It was mentioned in hints & tips (1/4 page or so) in MBM a month or two ago. Cleaned the props and a large area of concrete under the boat! :eek: I'll go and have a shuffle thro' the "pile".

September Issue, page 67 (over half page actually!) Starbrite Boat Bottom Cleaner, Force 4, £18.50 for 1litre.

Hope this helps.

Sounds good. The article suggests that the product is agressive and that personal safety must be considered (always a good idea).

Te hazardous ingredients are
Hydrochloric Acid < 25%
Isopropyl Alcohol < 5%

according to the product's Safety Data Sheet.

I can't stand the suspense of this; did Firefly625 ever find out what this miracle product is?

Did he use it?

Did it work?

If not, what will work on the brand new 3 bladed prop on my boat (hull speed under 10kn) ?

Imay not be lifting out for a year or two,though I may scrub between tides, so what will work?
 
I posted above last year that I was going to try both Propshield and Lanoguard
This is what I did

Answer was neither of them worked.
The Propshield (Industrial version) was MUCH easier to put on and I'm being a bit unfair saying that they didn't work.
In fact using this approach was better than painting with primers and antifoul because the pressure washer found it easier to remove the fouling.

Strange though because this year, I've been talked into going back to paint on the props
A three stage process
First the Hempel 2 part primer
Then an intermediate primer
Then a VERY fast hard racing A/F (I cant remember the name of it but it's the fastest A/F Hempel offer)
A few years ago, I did try the Hempel 2 part primer and then I put some Trilux ofer it.
We are talking Props here
The Trilux came off but the primer was prety good at sticking
This is the ONLY reason for me to go back to painting
Otherwise, I would be using Propshield again - only because it's easier to clean / pressure wash

Sorry to keep you on the edge of your seat, in fact other threads have kind of superseded this one. But the basic info was, the chap I had spoken to just used a Starbrite hull cleaner on his props and for him that worked to clean the props and seemingly kept them clean for the season.... once I found out that he had not actually applied anything I sort of went looking for something to apply. I had used prop shield before but it was messy and did not stop some crusty bits attaching them selves to the prop.

So last year I used a clear coat antifoul spray, http://www.force4.co.uk/9073/Force-4-TK-Line-Antifouling-Spray-Clear.html once prop all cleaned up this was easy to apply (simply spray on, a 30 second job) and gave the prop a lovely gloss look, gave the prop s a couple of coats and end of last season boat pulled out and prop all clear of any crustaceans, it was jet washed and came up lovely and clean.

So highly recommended by me!

I used the same on one of my props last year, as the shop didn't have enough Trilux for both. To be fair I didn't meticulously prepare the props first, and I didn't use a primer, I just sprayed it on after powerwash and acid treatment, but they were pretty clean and bright, and free of any grease after the acid. The clear stuff hasn't worked any better than the Trilux, and I still needed to scrape both props a few weeks after the first decent run out. My guess is that if this stuff works for you, then Trilux will work equally as well.
