Anyone have experience with Warpaint?

My boat currently has warpaint on it, around 1.5 years old and pretty much toast now. Barnicles on it after 2-3 weeks these days.

Much easier for me to just stick with the same paint but I will be changing color from green to grey. Boat lives up the weiti river.

 

I've got worn out Ultra2 and will be going over it with Ultra2 to save any conflicts or priming.

It's coming up on 3.5 years old and lives in the grotty part of Westhaven so it's done OK.

Or maybe it's a sign the water quality is now that sh*t life struggles to live in it. When I was giving her a bum rub Anniv Weekend I was a bit shocked to see how much the concrete pontoons have been eaten away by what I presume is whatever is in the water. At the time I was in the water and thinking 'Will I need to turn on the lights tonite or will I be glowing enuff'.

I'd speak to a chemist as you can swap between AF's as long as some key ingredients match.

Hi Josh

We have vivid currently and is just over a year old and is absolutely stuffed! Waiting for our haul out in March when we re paint topsides.

We are going to change to Warpaint. I have heard war paint is tested in the River so should perform the best. I also had a boat on the grid next to me which has Warpaint which was 12 months old and hasn't been cleaned and the guy just used a light brush and cleaned it in 30min and I was on the water blaster for almost 2 hours.

I’ve used warpaint for years and really like it.

It can be scrubbed which is good if your racing

The travel lift guys always are surprised How easy it cleans up when I do a lift and wash.

I also buy cleaning product through the company so maybe I do a deal ?

Yes I’m happy with the look but the reality of cleaning to avoid looking scruffy might become tiresome. It’s Vivid White.

This is what I'm using...easy to clean. Will need a recoat shortly.

Oh that is strange, I am talking Tamaki river, Milford Creek and Westhaven I am getting three years at each currently -Yes the boats are raced so I am fussy -but dont scrub it wipe it . 25' light displacement keeler 4L, 10M heavier disp keeler 7 L

Any less and you will fail, I have no barnacles and only slime to wipe.

Talking about sanding antifoul, I have found using a tungsten blade paint scraper really handy for tidying up after water blasting. I have previously sanded (using No 5), but one of the guys in the haulout yard suggested I try this, and it worked a charm. Just takes a light run over to shift any lumps and bumps. I should say I'm not looking for a mirror finish but it was a huge time saver.

Update.

Hauled out this morning and waterblasted mainly slime and light clusters of tiny barnacles of what looks/acts/smell like #5 that is at least 2 years old.

I was pleasantly surprised.  A big buildup on the bottom leading edge of the keel and one water intake (toilet) has a mussel growing in it, other than that just what you would hope for after a year of indolent disrespect by the owner!

The #5 has been applied over something else and has not bonded well in a couple of locations.  After discussion, we have decided to sand and feather and apply primocon in those locations, War Paint applied direct over the rest.

Thinking is we will be out again next year for a full hull paint and possibly up and over the top.  We will do a full strip below the waterline then and set a new baseline that we can stick to after that.

Thanks for the great input and discussion everyone - feel free to continue.

I have war paint on the new boat which was supposedly applied in Feb last year and is absolutely stuffed now. Coming out at Easter and I will go back to Ultra 2 which is what I had on the boat just sold. I have someone who cleans regularly so the Ultra 2 seems fine in that scenario. I'll have to apply undercoat and I see the specs say 4 to 5 coats 😒. Has anyone gotten away with fewer?

I'm applying Ultra2 in a few days time and I'm going 2 coats over a water blasted well worn Ultra2. I'll load up the leading edges a bit more. I would do more coats but it's heavy ;)

Loving the enthusiastic facial expression ;)

Good colour matching by the way :)

Lifted Fogg this morning for an hours work on SD leg inc changing oil from GL5 to correct GL4. Took opp for a light pressure wash - after only 2 months the Vivid is showing a lot of growth. Maybe it’s the white that’s highlighting it more than black or maybe it’s the warm conditions or maybe Vivid is rubbish. Anyway, the painters took pictures to talk to the rep about it.

Gulf Harbour. But last few weeks since antifouling I’ve spent about 50% in marina and 50% around Gulf inc Kawau and bottom end / Coromandel areas.

With the water in marinas being hot growth is all on.

What's the thru hull midships that whatever come out of goes upwards, exhaust maybe??

I've used vivid on and around my strut area, along side 3 other paints as on the hull in various combinations over the last 3 years, trying to be a bit scientific about it.

the vivid was crap any way you look at it, smooth for racing but needs cleaning way more than anything else and barnacles love it.
