Didn't you have a nice blue hulled gel coated boat, memory not great and not been on in a while, is the new one gel coat?
Well we're now into August, so surely by any measure it should be time for a reassessment.
Although I vaguely recall some polish manufacturers used to claim "wash once a year" in reality I think we all recognise that's very ambitious, and experience has shown me that about 3-4 months seems to be the life of pretty much everything I've tried.
At least as far as beading is concerned, but even in maintaining some kind of gloss appearance, which I would regard as being a measure of the uv protection.
To begin with, how about washing all the panels just with fresh water, before you go using their recommended wash products on them?
Again, to me this would give an indication of residual protection, if contaminants stick or wash off easily.
I generally polish the boat about 3 times a year. Once at the start of the season around Easter, once on our main holiday usually June / July, and another final one to protect it for the coming winter, say September or early October. So for me any polish has to be able to last 3 months in the (English) sun, and 6 months in the English winter.
Looking forward to the update... I wonder how that nano technology is lasting?
Thanks Tony.
My view is that the interval for the next test should be determined by the results of this one.
What I'm interested in is what is the genuine product life in real conditions, so I know the absolute longest I can leave it between re-application, so I can plan accordingly.
That's not to say I'll always plan around waxing at the maximum intervals, just that sometimes circumstances (life) can get in the way and you think "I'll leave it for another week / month" whatever.
So if the max life is say 6 months I would probably plan to re-coat every 4-5, knowing that if something got in the way I still have a bit of time in hand.
So if none of the products have lasted 12 months in this test, we should shorten the reassessment interval to 6 next time and take it from there.
To be honest I can't really see any of the products lasting a full 12 months, that really is expecting a lot. But it's also probably a bit unrealistic. How many of us caring boat owners would leave it 12 months between waxing? We should reassess at monthly intervals from 6 months onwards IMHO.
Then it's down to an evaluation of ease of application vs price once the product life is known, to be able to decide a "best buy".
Personally, if you could show a product that did what it said on the tin and lasted 6 months I would be more than happy.
Have you put this test to any of the sailing mags? It might just go some way to recompense you for carrying out this research for which we are all grateful on this forum.
Hi Tony,
Just a quick "bump" to get your attention!
It's that time of year when I'm preparing my boat for relaunching at the beginning of March.
Which inevitably means polishing and waxing the hull to protect it for the coming season.
I'm therefore very keen to use the knowledge gained from your tests to steer my decision making in that regard.
So sorry to chase, but can we have an update please?
I did notice a video you posted elsewhere on the forum where you were buffing up the topsides of a boat and you used one of the products involved in this test. That spoke volumes to me, even though you were quite discreet in your mention of what you had used. I am seriously considering going down that route, and it looks like you've already arrived at that conclusion and are using it routinely in your business now?
Hi Trundlebug,
Apologies I havent displayed our results as yet, I know yourself and a few others are waiting.
Sounds a poor excuse but it's a very busy time for me at present, with many in the same boat as you and my commitments and promises to clients must take priority.
I have started documenting the final results, even as I write (at 01:57) the panels are behind me on my dining table with a dslr on a tripod surrounded by lights, whilst I drip coloured water onto each panel to measure the contact angle offered.
It sounds as though the results wont surprise you (my fault for the leak) and yes I made my decision in Feb, but there are 14 other horses to come in.
It's proving quite the learning experience just to get the camera to capture and display what my eyes are seeing.
Justification for an EF 100mm f/2.8L Macro IS USM? swmbo, unfortunately does not agree with this.
Rest assured they will be put up the moment I've finished, possibly over the next few days if this snow kicks in and grounds me.
