Will these work to seal my wood transom?

Re: Will these work to seal my wood transom?

Im not sure that is is relevent to your bear sealer questions but every night i keep seeing that thompson wood sealer commercial."if its strong enough for the waterfall its strong enough to be thompsons" i wonder if that stuff would be good sealer for the transom. chances are that the transom will see water. wonder if anyone here has used it.

I've spoken with a Thompsons factory rep on one of our construction sites and he divulged to me that Thompsons Waterseal is little more than parrafin (candle wax) and mineral spirits. This is ok for around the house stuff, but I want something heavier duty on my boat.

+1. You can get Spar Urethane pretty easily for about the same cost, and it will work muck better. Shoot even several coats of good ol Rustoleum Professional Oil Based enamel would probably be better than the Thompson's, especially if you thin the first few coats and let it really soak into the wood. With a little prep work, you can even use it to paint the boat itself. Good luck. Keep us posted.

Re: Will these work to seal my wood transom?

just a fyi

Are you mad at your computer, iboats in general, or those that replied ahead of you in this thread? Why all the CAPS?

If you'd like to use Thompsons, please feel free to do so. If you choose to use it, please start a thread with pre-application wood prep, application & longevity testing (with text & pix) for the wooden components of a boat that you apply it to. That way those that follow can use your testing data to educate themselves & decide how they'd like to proceed on their projects

s freud: IMHO, I agree with the several posts above that recommend using something other then Thompsons. But that doesn't mean you should or shouldn't use it for your boat build. It only means that those who recommend against it, wouldn't on their projects. I think most of them above also mention why they wouldn't use it.

The CPES sealer you asked about earlier is sold by boat maintenance product retailers. In fact, a very popular marine retailer comes up in the first few hits of a google search for CPES. But when asked, several people recommended against using it, and why they don't recommend it.

In several instances, many of the above also recommended what they would be using instead of either Thompsons or CPES.

What you choose to do w/ those recommendations against the use of a product, is for you to decide for yourself. Just like if I told you I preferred Merc motors to Johnsons & this is why...... Use that info to decide for yourself what you want to do based on your wants, needs, time frame & budget constraints.

I hope the Niagra Falls deck is around for a very long time, and Thompsons is able to sell plenty of their products for a wide range of applications. Just not on my boat or my boat build....

Well maybe I should go check Lowes for the Spar since they did not have it at the Depot. I actually looked again at maybe doing the wood the whole way across the back of the transom, but realized that my transom is not flat. If you look at the picture of the inside of the transom above you can see that it bubbles in (intentionally from the factory). So I don't think I can do a transom the whole way across. Also, on the right side is my manufacturer plate with serial number, capacity limit, etc, which would be covered by extending it the whole way across.

Edit: correction, it bubbles toward the exterior.

Like this:

If you make a set of those clamps and put in one piece of 3/8" ply at a time you should be able to bend it to the shape of the transom. The reason that I had to sand mine so much is because I didn't know there was a curve in the transom and I glued mine together on a work table so it would be straight. When I put the transom wood in to dry fit it I noticed there was a huge gap in the middle and I didn't want to start over and make a new one so i just sanded it to fit. You can see the gap in this photo:
(Pix removed, wrong detail)

The current last few posts deal w/ installing 3/8" plywood into a curved transom. Just be absolutely positive that it's supposed to have that curve before you make it permanent. A soft rotten transom could sag under it's own weight, or damage, whatever. If the transom curve is matched in the cap it is likely that it's supposed to be that way.

Read thru

EDIT: I apologize, I got my tin & glass boat threads mixed up. As Jig has posted, a flat straight transom would be correct.
None of that I minimized is correct for a tinny:facepalm:.... I apologize, thanks Jig


I'm surprised the Depot didn't have exterior spar varnish in the paint dept. But it might have been spar urethane. Lowe's should carry Cabots Spar Varnish:

When you start a thread for the resto, leave a link here to it

... and that would be a bow from running a motor on a rotten/weak transom. This can and should be straightened out with your transom wood core spanning from port to starboard sides. 2 pieces of 3/4" plywood laminated together will take that bow out of your transom and make it nice and straight like it should be.

We're not trying to make life difficult for you, we're actually trying to help you.

Re: Will these work to seal my wood transom?

And I absolutely appreciate the help. When I say it "bubbles out" maybe I am not using the right terminology. If you look at the picture below the transom has a factory "dent" outward. the words "side" and "kick" are each on the "bubbles." You can also see under the picture where the depth finder is where it pushes out. See what I mean?

Re: Will these work to seal my wood transom?

The 14X14 pc only covers the center area that matches where the exterior pc was attached previously, correct? This is more likely a jon boat type boat w/ a couple bench seats that are fabricated out of similar tin. And you'll likely be running a lower HP tiller motor.

We may have over thought this:facepalm:

Start a thread for this boat that replaced the 1 that had rivets torn out that got sold. And we'll try again:facepalm: Sorry, again

Depending on the motor you plan to use, if I'm correct about the boats size & type, will dictate the transom that's needed.

I need to take a timeout, this is my 2nd apology in this thread this evening:facepalm:

Any more pix you have of the new boat, post them as well. Thanks, we'll try to do better by ya over in the new thread... And again:facepalm:

Re: Will these work to seal my wood transom?

No apologies necessary. I should have posted some pictures early so we were on the same page. I will start a new thread tomorrow after I takes some pictures of the entire boat to put up. I'll throw a link in here to the new thread. Did some cleaning and prep tonight which was fun. There's a thread on here about keeping your engine pegged for too long, what about your drill with a wire brush?

Edit: Unless I it will be in the wrong place, I plan to put it in the Sears forum category as opposed to the resto. category. Or will I receive more feedback if I am in the resto forum?

When the metal bristle count in your jeans/legs matches the bristle count on the wire brush, it's time to stop & change the brush:facepalm: Much more common when used with a grinder

Well I am glad that did not happen as I was wearing shorts!

Here is the link to the new thread guys with more info on the boat. Thanks for all the help and see you there!
