Re: Hull finish - Smooth as glass?

It looked to me like someone slapped on a quick coat of bottom paint without bothering to remove and fair the areas of loose paint beneath it. I wouldn't see it as a real big deal but it is sloppy and may reflect on the way the boat was maintained overall. Or, since the boat is for sale, it might have been something the broker arranged at a bargain price to dress the boat up a bit compared to before it was painted. Not impressive, but not a biggie either, and not too hard to greatly improve with a putty knife and wire brush and electric sander with attached vacuum, or a wet Scotch Brite pad if it's softer, ablative paint.

I'm a fan of ablative bottom paint and doing it myself. I wear long sleeves and rubber gloves and only do it outdoors so ventilation isn't an issue. I've found that having it done by a "professional" usually means the newest high school kid to get hired at the yard, or the adult worker who is incapable of anything more complicated, who is getting stuck with all the jobs nobody else at the yard wants. I'm pretty confident I can do a better job and using ablative paint it doesn't take nearly as long to prep as with hard paint and since it's only once a year for a few hours, I'm not too worried about the short term exposure to the toxins. Since I'm using ablative paint, I never have to strip it or use a sander, just a ScotchBrite pad and a bucket of water to keep rinsing it in as I go over the whole bottom before painting, so there is not dust to breath. Works great!

Re: Hull finish - Smooth as glass?

When I do mine I vacuum sand wearing my space suit and protective gear, then re-apply new products according to instructions, also wearing protective gear. I am very happy w/ the results.

Re: Hull finish - Smooth as glass?

When we did the last job I was a bit careless with my protective clothing. I ended up smearing some of the sanded dust on my forearm, and then accidently rubbed this against my temple, clearing the sweat out of my eyes. By late that afternoon both patches of skin felt like they were badly sunburned.

I will be a LOT more careful next time.

Matt

Re: Hull finish - Smooth as glass?

Has anyone used Toon-Brite Protective Clear Coat ?
It says can be used on hulls , topsides , etc.
Its for marine use and the spec sheet looks very promising .

Any thoughts ?

Thanks Steve.

Unless you clean and polish the bottom once a week it's about 2 feet from the bow what needs to be "smooth". Boundary layer at the stern is 100 folds a hair..

Re: Hull finish - Smooth as glass?

The barnacle bases on the sail drive are a nice touch and a dead giveaway that it's a "Wham bam thank you Ma'am" job.
