please help - paint newbie
Good afternoon all ,
I received a coronado 35 and have to repaint the bottom as well top of the boat.
However I just made some pictures and like to ask if somebody could give me an advice which paint etc. how to apply?
I have no information about the past of this boat.
under the bottom paint is a grey (paint , gelcoat ) or may the polyester itself.
However all your help is very welcome ....please see below some pictures.
Could you please take a look to the corrosion and give me an idea from where the corrision is coming:confused:

P.S. sorry for all the questions but having professional advise here in this area where i'm living seems to be very complicated.:hothead

Hopefully you'll get folks with a lot more experience to chime in. But to me, it looks like the bottom could use some repair, too. Maybe that's just the bottom paint peeling away in some of the pictures, but to my (very novice, and untrained) eyes that looks like something scraped it. It may not be all that hard or expensive to fix, and it may not be structural, but I don't know that it's the best of ideas to put her back in the water in that condition. At the very least, she'll be slower with all that roughness around and under the water line.

Looks like a lot of work.

The marks/'corrosion' on the bottom might be simply from dirty travellift straps - in any event they'll clean up easily enough.

More concerning is picture #3 (damage to the green topsides)... looks like puncture holes and severe dock rash or worse. That's some serious f/g repair and fairing work required.

Is this a hurricane boat? Did water get inside? More work still if that's the case...

Judging by the fender rub (dark bruise in the green in another shot) I don't think this is any special sort of paint, but it does look like paint to me.

As far as what's there already, since you have no way of knowing you'll just have to try a sample of what you want to use next on a small area and see if there's any reaction/lifting or other reason not to use it further. But if you intend to repaint all the green topsides I think that paint has to come off, so that you can start fresh.

Best of luck...

Don't let this cut into your sailing season. If you don't have time this spring, do the bottom this year and topsides next. Removing old paint, and painting topsides takes a lot of time.

Re: please help - paint newbie
Like Faster suggested your boat has some "dock rash" where it is mostly
cosmetic damage - that should be fixed eventually. The deeper holes would be
good to fill with a thickened epoxy, to keep water out - which is pretty easy to do.

The bottom does not look so bad to me. Scrape off any loose or peeling paint.
Give it all a light sanding (if you dare).
Wipe it down with Acetone or de-natured Alcohol.
Repaint with antifouling paint.

Regarding which bottom paint.
If you run a clean rag over the bottom paint and some of the color comes off
on your rag then your boat was last coated with an ablative, or soft paint. If a
soft paint was last used then that is what you should use again. You can't put hard
bottom paints over soft ones in most cases.
If the bottom paint is hard then you have a choice of using either a hard or soft bottom
Since I don't know whether your boat will be in fresh or salt water, or where you will be
sailing I can't recommend a paint for you. You should use the type of paint used by most
other boaters in your area as they already have a good idea of what works where you are.
Cute puppy by the way.

Re: please help - paint newbie

While something metal on deck can cause rust stains around here OAK LEAVES are the leading cause of bottom paint streaks

You have ways to go on this boat and I have done both and been happy with both

1. Paint the bottom and do basic seaworthy repairs go sailing soon

2. Take two years off for refit and still go sailing on friends boats at least two times a week to help remember why your working so hard on boat

Seafever is the last boat I will ever own after a lifetime of owning boats which is why the time was invested to make it what we wanted

Re: please help - paint newbie
On the topsides, fill any deep gouges with some epoxy filler to protect the glass fabric. Scrape the bottom with a good two handed paint scraper and put fresh bottom paint on per the advice given previously.

Assuming the boat is just cosmetically challenged, go sailing and do some extensive reading on boat refinishing over the summer.

Next fall you will be in a position to know what you want to do with the boat. A Coronado 35 has a LOT of topside surface to paint so you want to be sure you are well prepared and know exactly what you want to do.
