bottom paint
 

ok since its supose to be nice on wensday i plan on pullin the boat outside and preping the old bottom paint for a new coat
its a trailer boat now some time ago someone bottom painted and slipped it Its has gotten to look like crap id perfer real paint but a new coat of bottom paint would suit me just fine.. as i plan to maybe do a few weekend trips 2-3 days straight in the water so i dont see it hurting.. you can see the flat black looking old paint with white showing threw thats where is flaking off and wore though

Plan of attack is a electric palm sander and 60-80 grit sand paper i hit a small spot earlier and it comes off pretty easy
any one else have any recomendations ??? hints tips i beleive this ablative paint on it now as it rubs off on your hand also beleive its only one coat of black maybe a white primer.. what should i go back with .. and should i sand all the black bottom paint off or just smooth the worn spots out and scuff the rest up for a re apply

havent bought any paint yet id like a gloss black to match the real paint on top any such thing any certain brands or ???

I also would like to know. Hey how do you plan on supporting the boat and removing the trailer so that its safe to get under to sand and paint?

Have it soda blasted and get all theold paint off. Buff the bottom and it will be close to good-as-new. Unless your keeping it in the water, get it stripped. You can get it done on aboat that size for around $700. 2 gallons of good ablative paint are $230 each. It works out in the end.....

ive took them off in the past and blocked them but im just gonna leave it on trailer and lower the bunks one at a time..

its not originally black underneath the black bottom paint... itll have to be repainted with something.. dont have the dough on for the blast reason im doing it myself

fixx
 

if you can rub it off with your hand i would get a box of razor blades and a razor scraper,scrap off all the loose stuff and try to keep the razor blade as flat as the hull so you dont gouge it..then with your palm sander use 220 0r 240 grit,80 is kinda harsh..

Gotcha. Another option is to sand it down as far as you can before damaging the fiberglass. Barrier coat it and use a hard anti-fouling paint. They come out nice and shiny, and will help with growth. be prepared though. If your going to sand with a hand sander, make sure you wear goggle, mask and coveralls. It is HARD to get that paint off your skin. I was sneezing bottom paint for days afterwards.

and that damn zinc/copper taste that goes with it.

1+ on that! Back in the day I worked for a local shop doing fiberglass work and bottom repaints. I had a full face respirator, full Tyvek suit, gloves, etc and I taped all the seams and I would still have that taste in mouth. And that was with new filters and Tyvek suit everyday.

Its nasty work but you will save money doing it yourself, I recommend getting all the proper gear before starting. I could not even imagine doing it without all the proper gear.

lol yea ive tried a few tests spot sneezed for a hour..lol

i dont know what the origanil color gelcoat was as seems like there is a white primer under the black the black is thicker than the rest it doesnt seem like very thick layers

i have a electric palm sander and of course masks etc.. using 60-80 grit knocks the black off/smooths the bad spots out fairly fast.. im not knocking it down to original gel just smoothing in the black /white and knocking down the rest of the black some then gonna repaint it.. hopefully with something glossy that i can roll on not super worried about the bottom as long as its coated dont see much of it anyways just hate the way the old looks on the trailer makes the boat loook like crap.lol

im gonna try and do it tomorrow and thursday

anyone see any problem with using just the hard antifouling over top my prepd surface... i think whats left on it will be enough of a barrier coat..

1+ if you do good prep work and then good hard antifouling you will be good to go.

Get a can of easy bake oven cleaner.... spray it on there see what happens.......you will be pleased....dont get the cheap stuff

yea ive used strippers and razor blades before on stuff with 7-9 layer on it before and it worked great for gettin all of it off

for this its only a 1 base and primer i want to blend and recoat im gona stick it out with the sanding granted if it was super thick or layerd like no other id be stripping it off

Jason...buy or borrow the best respirator you can get you hands on and cover up really good. That mess is NASTY and will make you sick as a damn dog for days.

You don't have to get really serious with the sanding. Get the worst spots sanded and spot primed and get the rest cleaned up enough for paint to stick to it. Get a couple of cans of Interlux or something good...put it on in sections with a small roller. It's self leveling and turns out pretty good. Pace yourself and don't try to get it all done at once.

I did my 40 Foot Sea Ray a few years ago...I don't want to fool with it again.

it is worse than nasty. why do you think marine life won't stick to it? it is POISON!!! barnacles are smarter than us! they don't go near it. DON'T BREATHE IT!!!

I had a 242 with really thick nasty bottom paint! I stripped all off, I tried everything, pettit, back to nature, west marine, nothing worked as good as Behr deck stripper from Home Depot. It didn't harm the fiberglass at all. Just rent a good powerwasher with a rototip nozzle. The stripper is $20 a gallon and you may go through 6 gallons.

If you get all the paint off first, OR prime and barrier coat over the ablative, then you can put the hard bottom paint on. The only paint you should put over ablative is more ablative. Trust me, I have been down this road before.

The white could be the original gell. That is how formula painted them back then.

If your going to go thru all the trouble to strip it all off and blend it in, why not just have it painted with some good shiney paint( I don't paint so I don't know what product to use) and be done with it. You did say that it's a trailer queen now right? A few days left in the water on an occasional trip shoouldn't hurt it. Bottom paint blows for looks, speed, and maintenence. Do it once and be done with it. Just my 2 cents.

well i plan on repainting the whole thing in a few years and i didnt want to just recoat what was on it just makes it that much more built up used a few cans of oven cleaner and power washer knocked all the loose off pretty good know its not nearly as bad to sand just gonna knock it smooth and reapply something better then if i repaint ill knock the whole boat down when money allows...

Have you tried this stuff? It looks like it really works without damaging the bottom of your boat.
