Remedial hull rehab question - help!

[RHB]

Oh ye learned all -

I’m in the process of rehabbing a CD25, and have completed a few initial steps (wood, some wiring, misc. hardware). Now I have to do the hull. Argh.

Here’s the deal -- the hull hasn’t been looked after in a long time, and has all sorts of little things to address. There are some hairline cracks here and there, a goodly amount of oil smears and hardened drips of God-knows-what, some green gook that I can’t hazard to name, and so on. I’ve been searching this list to find the right chemicals and techniques to address all of these things, but (other than On/Off to clean the gelcoat, and plastic putty knives to scrape, and a hairdryer for the old lettering) I haven’t come clear on what to do. So can I beg your help? Here’s what I need to do:

1. Remove hardened oil, varnish drips, etc. from hull
2. Remove other stains
3. Fix hairline cracks
4. Clean and wax

I have a large can full of chemicals (adhesive remover, stripper, paint thinner, naptha, Heineken) and a similarly huge bag of abrasive sponges, scrapers, putty knives, etc. And Lowe's is just down the block.

Can anyone help me to make this simple? I’d bow to your feet.

I'd start with something like liquid detergent and lots of elbow grease then WD40/diesel fuel and work my way up to say MEK. Be careful and use MEK very sparingly. If MEK doesn't work it's part of the gelcoat and will need to be ground off. If left on the gelcoat MEK will most likely soften it up. It's nasty stuff, but not much can't be removed by the careful application of it. You don't want to breath it.

Rob,

For 1 and 2 i used soap for the dishwasher with great succes. What i did is:
1.Wet the hull
2. Wet the rag
3. Dip the rag in the dry powder
4. Clean the hull

I tried to always keep a good amount of dry powder when i rubed the hull and i used a spray bottle to keep the hull wet where i was rubbing

I'm pretty sure that something like "Ajax" will give the same result.

A BIG WARNING..DON'T DO THIS IF THE HULL IS PAINT.
I did it on my paint deck, it look great for 1 day and i must say that i was so happy... The next day the paint had peel.

Take your time, one item at the time and at the end the job is done.

Good luck

Marc

A combination of liquid deteregnt and chlorox works well, for brown stains from saltwater infusion around water line or rust OSPHO or Lime away, who now has a thicker formula that clings, both must be rinsed well after a while read directions of course. I have also used silver polish on stubborn stains, the silver polish stated " for use on fiberglass" on the container. I think it was Wrights Silver Polish

Hi...

i teach this to ever one.
thats what i do for a living and i am a manager of a boat store. and i restore old boats on the side.

the first thing i would do is wash it with shaving cream the kind that you use on your face and get two or three cans, you can use it on the whole boat if you want then wax above the water line only..

all you do is use a blue grade brush and the shaving cream, scrub then rinse and go all the way around the whole boat twice until you get all most ever thing off,
it may not take ever thing off, but thats ok.

then take a bottom cleaner to it which will remove all the rest using STAR BRITE bottom cleaner, again use a blue grade brush and wash the whole bottom, make sure you wear gloves and eye wear.
and do it twice.

then when you are done, if the surface is not smooth lightly sand the whole thing wash the boat and let it dry.

then you can put a barrier coat on using vc tar or 2000 and 2001
two coats on. read the cans.

then prime with two coats and two coats of bottom paint.
read the cans.

in fresh water i tell them to use vc17 or sr 21.
in salt water use vc 17 off shore or ultima sr.
but the best paint on the market is pettit vivid and it has allot of different colors, but the price is very high $160 for a gallon.
thats what i put on.

but there are allot of good paints out there so you can ask which paint is used in your area.

i hope this helps and if you have any questions just ask.
