O'day hull resto

[alpar80]

This is what im up against. The mock up is where I sanded using d.a. 40 grit, I believe the red paint is red lead. You can also see the areas of failing and chipping. I am sure there is blistering and am not too concerned with scuffing it up. What is the most economical way of restoring this hull? I do not want to scrap the boat, it is sentimental inheritance.

My I phone submitted the pics upside down but, you can get the jist of the damage.

Anything is fixable, depends on how much time and money you want to spend.

Re: O'day hull resto

What boat? Does anyone see a boat? Pics of the entire boat would be great. Is this an O'Day sailboat? What Yr, Length, Is it wood or glass? Really hard to tell exactly what you're dealing with form those pics and description.

O'Day sailboat . . . looks like a fixed keel . . . but let us know for sure.

the pictures look like just different layers of bottom paint. So, the thing to do would be to use a paint remover (Peel Away, oven cleaner, etc) and remove the bottom paint (won't be the most fun you've had). then, you will get a good look a the hull and determine if there are blisters, etc.

The boat looks like it has been in salt water, based on the bottom paint and barnacles. Blister formation is more prevalent in fresh water.

So have at it with removing the bottom paint and let us know what you find.

Re: O'day hull resto

It's a 20' oday with retractable centerboard. I have access to peel away even a sandblast pot that I use for work but I cant introduce soda blast to it. I did a mock up with 40 grit sand paper and got it to the gel coat however, it scored it. I am thinking that if there is blistering that I may just want to start from the beginning with epiglass and use interlux interprotect 2000 as a barrier (or a similar product). Would you recommend using 40 grit for the whole hull and starting fresh or using a chemi peel, salvaging the gel coat and applying a barrier coat on top of that?

Re: O'day hull resto

Use chemicals to peel away the paint. Then, you can see what condition the gel coat is in and plan from there.

i don't think that 40 grit is going to serve you well. . . Not the right thing to do.

Use a paint scraper and get as much of the old paint off as you can. Try it on an angle with pretty good pressure. I restored the hull on my chris craft and scraping was the way to go. After scraping I used a da sander with dry "film discs" to get the last bit of primer and sanding marks out and restored the bottom to look like new.

I did try like 5 different strippers and non of then worked well. Its all in my rebuild thread. The paint on the bottom of yours is already chipping off in spots, I would start in those areas. Good luck

I tried many different scrapers before i found the right one. The one farthest to the right in picture was the best on my hull. Got it at lowes in paint department. Its very stiff but had a nice edge.

Re: O'day hull resto

Alpar, -- About your comment/ concern of " I believe the red paint is red lead". No it is not. Bottom paint contains cuprous oxide (copper), NOT lead. Red lead was / is used on the inside, and between some components of some wooden boats during construction. Nothing to do with antifouling bottom paint.
I agree, 40 grit is WAY to course, unless you are real good with a disk sander & don't go all the way through the paint into the gelcoat.

Re: O'day hull resto

What about if I were to re apply gelcoat?

Reapplying gelcoat is a hard and long process, and its not neccessary if you can restore the original. Are you planing on putting bottom paint (anti fouling) back on this? If so you won't have to worry about scuffs in the gelcoat because you will be scuffing it anyway for a good bond.

Re: O'day hull resto

Yes, I am planning on applying a barrier coat i.e interlux interprotect 2000 and than antifouling on top of that. As you can see from the pics above, she is quite nasty down there...
