Cleaning latex house paint off V-1

The people remodeling my neighbor's house painted recently, and some of the overspray got on the bottom of my V-1 (Tiger Tevanui) hull.

What is the best way to get the dried latex paint off without damaging the gelcoat. I can scrape small areas off with my fingernail without any apparent damage, but that would take a long time to go over the whole hull.

Some sites relating to furniture repair suggest that lacquer remover, alcohol, Goof Off, Goof Off 2, and Simple Green can be used to remove latex paint, but will these damage the gelcoat?

Once you clean the hull, kill the neighbor and string up the painter!@#$

Acetone, denatured alcohol if your a wimp, or goof off. It will take a lot of work to thin the gel coat, but if you notice the gel coat coming off or burning through try something else.

you can try lacquer just add little bit water..... try in a small area first...I used lacquer to wipe down my truck or try simple green.

Easy on the painter please.
Alcohol is your fastest way to go after dried latex paint. There is another product I swear by for this kind of stuff. It's called "KrudKutter". It's water based and advertised for the exact purpose of removing dried latex paint. Just pump spray it on, let it soak a bit and take it off with a soft cloth/sponge. Don't use scotchpads, too rough. Krudkutter won't harm your surface, but since it's also a degreaser I would wax/polish/secret-sauce it when you are done, to close the pores. Lacquer thinner, acetone will do it too but the gelcoat will dissolve faster then the dried latex and it will then EAT your gel/automotive or whatever coat you may have.
If you want to lazy up "my" process, wrap a bed sheet/towel etc. over the affected area, keep it moist with Krudkutter for about 1.75 beers and it should come right off.
Patience will be your best friend.

Toa Moana... did you have to use the word wimp?

Endust spray just might do the trick. I use it on all parts aluminum: pedals and na iako (please don't pluralize Hawaiian words, mahalo).

After using the KrudKutter, and I want to seal up all those pores again, is car wax the best thing to use on my hull? A friend of mine swears by wiping down the hull with WD-40, but I don't like putting that stuff in the water...

What's the fastest coating, (or non-coating) that I can put on my hull?

Love, goto.

Definitely not WD-40. Car wax will do in a pinch, but might not penetrate deep enough into the gel coat pores and start some oxidizing under the wax. Vertglas or Poliglow are one of several choices specifically designed for gel coats in a marine environment.
It'll make the boat shiny again. Of course we can at this point resurrect the discussion about laminar flow in relation to coarse surfaces vs. slick and the speed gained or lost in that.
For the purpose of preservation and protection from the elements, shiny beats dull.
I've done some of my best racing with a shiny boat. You rub her, she rubs you back. The time you spend making her pretty is rewarding in a zenish kind of a vibe just as much as taking the tried and true medicine called placebo, which has made manufacturers of sugar pills so wealthy.

All I need to do is rub her, and she'll rub me back? Incredible painteur - if what you say is true, then you've got mad game. I'm going to try it out on some unsuspecting lucky ladies at the coffee shop tomorrow morning. Look for live updates on how things are proceeding on Mindy's blog...

But seriously, THAT'S what I was REALLY asking, which is faster, the smooth and shiny hull, or the wet sanded, "dull" hull? I would appreciate it if you could just give me only the correct answer please.

You know, get this Maui paddler, who stay always polishing his canoe on the beach with Turtle Wax before the race. He swears by it from experience using it for years on his surfboards (says they run faster on the wave). And on Oahu, he does the same thing, so who ever loans him a canoe is lucky, for they get one shiny canoe back after the race.
ps: I tried for tell him that the wax actually re-formulates in salt water and slows the canoe down.

Dull hull is faster, I just don't know what reaction you get when you go at "her" with sandpaper, no matter how fine the grit.

No can beat them long john Speedo "Fastskin" swimsuits. Sure would cost big bucks for glam on a bunch of them on my canoe? I wonder if they make em in Hawaiian print?

our ancestors up here on the west coast would make groves 1 inch wide or so. through the whole canoe end to end and would say it Chanel's the water, and would swear by them and Ive seen it work. it would make the canoe faster. much like Chines

well the top boat builders sand the bottom of their boats before they race big events. then they wax them.
i know this one guy on my island who has an ultralite boat with a practically clear gelcoat, that kai used to own, and the gelcoat is almost nonexistant because the hull has been sanded so many times.

#14 Mon, 03/30/2009 - 12:19pm

what type of wax?

#15 Sun, 04/05/2009 - 10:42am

ive seen them use surfboard polish, then carnauba wax
but i think the surfboard polish is only used on boats just out of the mold..

mahalos for that advice

#17 Sun, 04/05/2009 - 1:34pm
