I don’t know anyone who has one anymore.

dnice, your right, I’m not so concerned with a “yacht” finish.

cheers

Alex

It would require a lot more prep work just to keep things under control and looking good.
I once accidently speckled the side of my contractors brand spanking new truck with KILLZ! from about 30 yards away while cleaning out an airless :)

Not to mention, its the cheapest and most portable method.

You really won’t be too worried about that ‘yacht finish’ once you get down south a little ways :)

Hey Alex, know anyone who needs a bunch of MD11 parts? :)

I’ll make sure to bring extra paint for touch ups. I’m planning on mixing it with nonskid as well. The mothane will still be al ot better then the one part poly, right?

After putting on the epoxy with a roller, I’m good with the roll/tip idea.

Cheers.

They are made for thicker paints, your mothane, when mixed will be just a little thicker than water.

Scuba tank is 80 cubic feet at 3500 psi, you need steady continuous 8-12 cubic feet/minute at 100-110 psi and a properly adjusted gun to get the paint to atomize properlyl, lay down and flash right. It’s not that hard and you do not need a high quality gun to do it. The $40 one at Walmart/Lowes will work just fine. Having the kind where the gun is separate from the tank is preferable to the one where the two are fixed together and is much better for flat work, the tank will drip when tilted, I promise, which is not a problem if the work is vertical but a big problem if you are aiming the gun at a horzontal surface. Mothane, I’ve used it several times on my whaler, is a great alternative to Sterling/Awlgrip but it will not flash and give that gloss anywhere near the same so spraying will not yield substantially better results than roll/tip. It is also nowhere near as hard and tough a finish.

My 2cents, roll and tip. Much easier, much cheaper, not much masking and from over three feet away you wont be able to tell the difference. and with mothane you will be repainting sooner, particularly on wear surfaces like the deck. The bottom of my whaler is scuffed up enough to see the primer in places in a single season, you will be on your decks every day. Buy extra and touch up frequently.

Good luck and go sailing.

FYI Wayward Angel had a fantastic sail from Ft Myers to Isla to Belize to Guatemala where the boat is now. I came back home to work for a while but am heading back in April.

And contrats on your new family, you were overdue for some stabilizing influences. ;)

HEA

With that said I don’t see why you couldn’t use an airless sprayer, people use them with Awlgrip and I doubt Mothane is that different. Who told you it wouldn’t work?

Cheers, Dave

The guy I spoke to in Panama had done 2 coats of his 38′ boat with one tank. A dive tank has a lot more compressed air then a paint compressor tank. I would also put a water filter in line. The problem I have is expense. I’ll need to paint sections as I want, and don’t want to do a long term rental, and buying a 100 gallon compressor & tank isn’t really an option. I wouldn’t mind having a 30 gallon compressed air system on board for tools, but I don’t think it would be sufficient for painting??? After all this I may just end up rolling & tipping.

I don`t think that I would do it like this! I would hire a decent (proper painting) compressor ( with moisture filters etc) for a couple of days, after all it will only take a few of hours to spray the whole boat with the correct preparation and equipment. may be go to a paint shop and watch how they do it and ask questions you never know, they might offer to do it for you if you prepare it?
