Caulking Question?

I have a Billing wood boat that I built about 30 years ago. It has been 20 years since it has been in the water. I want to put a new radio and drive system in it and be able to run it again.

But there are cracks in the paint on the hull. The hull is planked mahogany. If I remember correctly I put the planking on with epoxy. It was then painted with regular enamal paint. I am getting ready to sand off the paint where necessary.

My question is? Can bathtub sealer(silicon goo) be used for calking? I know that white glue covered with enamal is OK if the glue is allowed to dry out between running secesions.

I take it that you are looking at using the silicon to fill in defects that you may find when you san off the paint?
There really is no reason to treat it any differnet than you did many years ago when you were young and able to see the defects in the hull.
After sanding the paint off, why no come back with wood filler for the defects, cover with laquer after sanding and then finish with what ever you wish to cover the boats with.
In our combat ships that often have cracked hulls( even on the fiberglass sections) we will sand, laquer, fill, laquer and then ( depending on whether it is glassed or balsa) resin or paint.

Silicone does not take paint well.

Hey, if you are in Seattle, check out
Northwest RC ship modelers Club
I believe they meet at Galaxy Hobbies in Lynnwood WA.

Hmm, don't let their web site ISP download anything to your comp either. Looked like an adware prompt.
They need a new ISP,...

I have already made contact with the NW Ship Modelers. I am going to go watch one of their Fun Floats today.

I have sanded off the paint on several of the splits. One is real bad. It will take a piece fo glass tape to repair. But the others are minor cracks under the paimt. I am looking at dilluted TitebondII to seal these cracks. Epoxy won't flow into such a small crack.

This is a wood planked hull. It is built using real Phillipene Mahogony planking. But after the boat was fully asssemebled there is minimal interior access to the hull. So all repairs mut be made from the outside.

Just not going to be a "Quick FiX".

This boat originally had a slotcar motor in it. I am replacing it with a S-280. It also had an old single channel 27MHz radio. And I do mean OLD. It was not proprtional. I am replacing it with a small Futaba 2Ch AM radio. Because it is the smallest 75MHz system I can find.

Thanks for the comments.

Take the Mercer St Exit Off I-5 I think.

Talk To Cliff Shaw if you get a chance, He will tell all about repairing and rebuilding your boat.
He is part of the group I sail with. And we bug him all the time for great wisdom, and knowledge.

Well I found the Center for Wooden Boats. And I watched them run for about an hour.

Then I came home to put some effort into repairing/re-furbishing this boat. I am going to try and have it ready for the Fun Float next month.

If this were my boat I would go to West Marine or Boat U.S. and buy a tube of 3M 5200 caulking and use that fill the gaps. This is incredible material, but don't plan on removing it later, it won't come out.
