Good logic as always I'll give them a call Brian Sounds like a plan. It's a small business and sometimes the owner Jeff answers. Their website isn't the best to find info on the welders, but the online PDF catalog is a good summary and easy to read: www.usaweld.com/v/vspfiles/pdf/HTP_Catalog_2018.pdf |

A diamond insert cut that hardened gear like butter. Expensive $50 for the insert and it has only one cutting edge not 3 but it worked. I tried carbide first and that was a joke bounced off it.

Graco TrueCoat 360 VSP handheld airless sprayer. It sprays on bottom paint (copper stuff Woolsey Yacht shield) straight from the can. I offered $132 and they accepted: www.ebay.com/itm/283676807845Now that I got my system set up, I can probably get through a gallon in 20 minutes if access to bottom of boat is easy. I leave paint in it over night between coats. |

Do you think it will spray gelcoat?

Airless sprayers shoot nothing but MESS. I helped a pal do an unfinished basement ceiling (open joists etc) with a top shelf GRACO unit, in black latex, and we both looked like Amos and Andy. Yer a kid Krush... roll it! Of course as penisis recomemnds, sand it and burnish the old stuff down to 2000 for better speed and economy. Yeah, right. ws

The problem with airless is you need pressure to atomize then you you need volume to support that pressure. I'm guessing but probably for typical bottom paint 2500 PSI at 1 gallon per minute that's going to be a 30:1 pump at a minimum. When it's right it's much cleaner than conventional when it's not it's a mess. To much detail or windy it's a mess. We use airless on the hull exterior only it takes our painter around 2 hours per coat and that's around 20 gallons and 20 minutes on trigger time the rest is moving and positioning.

I don't know if the gel coat could be cleaned after use. Acetone is pretty tough on plastic.

It probably can shoot gel coat, but you gotta be good on cleaning it. My friend said he shots 2part epoxy through his similar model (and then his worker didn't clean it, so he had to buy new pump guts lol). This bottom paint was shot straight from the can. I left it in overnight because it seals paint from air.
The paint gun says ~2000psi maximum. It works fine for bottom paint. I use ablative, I just need to get it on the boat, it smooths out on its own. And because I knew you nay-sayers would say unpossible, I took a video!

I like the idea and have sprayed other types of paint before with the commercial paint sprayer for interior and exterior house paint. In the port we cant spray anything even touch up guns and preval sprayers are problems with the feds.
It seems that sprayer is as neat and more efficient than rolling for sure. That's probably why its banned. Maybe out president can share back the previous administrations bs and allow progress with common sense.

Overspray is not an issue at all as long as you got good aim and always point towards the correct target. The wind was howling yesterday and I was careful to make sure there was no overspray. I get more splatter on me when I use the roller. The paint is so thick it doesn't really atomize to make overspray.
You wouldn't want to shoot a hull side with it, but for bottom paint that is just getting globbed on, it works great.
