paint paint paint ugly bottom

[79santacruz]

ok so here it goes... i have a 1979 carver 28 foot santa cruz...it has several layers of black bottom paint from living in the water ... i now dry store the boat at my local marina and the owner suggested just letting that stuff wear off , but me being who i am and building show cars for so many years i cannot live with it looking like that and need to find a solution to painting it and repairing the old factory busted trim tabs i would like to put something on it that isnt cracked and falling off but it doesnt need to keep things from growing on it seeing as how it wont stay in the water for more than a few days at a time and help would be greatly appritiated

Ayuh,... The easiest fix for the bottom paint is More of the same... If ya want the good Looks...
Or, have somebody scrape/ waterblast/ whatever it off... Alotta Work to remove...

The trim tabs are probably Bennett's,...
Whatever brand, replacements, or parts shouldn't be much of an issue...

I would remove the old AF paint..then prep/coat with 2 coats of Interlux 2000..then put 2 coats of VC17 origional on it..

Just me though..

Re: paint paint paint ugly bottom

I agree with Bond-o and WD- remove all the old stuff first.
Choices- sanding, scraping, sand/sodablasting, chemical stripping. All are difficult and time consuming but necessary for a proper job.
When I stripped my 25 year-old boat bottom I intended to have it professionally sodablasted but ultimately couldn't afford it. I tried chemical stripping but discovered that hand scraping worked well due to the 8+ layers of antifouling that had been built up over time. I spent (literally) 4 full weekends on my back wearing a space suit, mask and goggles and was able to get all the heavy stuff off. The next 3 weekends were spent with 60 grit in a palm sander getting it ready for barrier coat.
The EASIEST part of the job was the application of the new barrier coat and bottom paint.
In your case, I think a full 10 mil application of barrier coat would do the job if you're rack storing.
Here's some pics:

Re: paint paint paint ugly bottom

thank you for the input, if it was in the water all the time and i couldnt see the fat mess of bottom paint it wouldnt bother me so much. but the fact that i have spent the last 12 years painting show cars and making them nice it drives me crazy ... the barrier coat is what i am looking for couldnt find it online (i dont know the names of the stuff) is that what yacht DR. is referring to ? i guess i cant put my boat on a rotisserie like i do cars to do the bottom so i guess ill know what Michaelangelo felt like

Yes, the barrier coat YD mentioned is Interlux Interprotect 2000E. It's a 2 part epoxy and what I used on my boat before applying the antifouling paint.
I rolled it on and it was pretty easy.
I paid $100/gallon for the 2000E in April '09 and took 3 to get 10 mil thickness on my 34 footer.
