Walls over wheel fender

[Walt M]

Ok all, I'm building a new TT. I'm going to cut the walls over the fenders but I'm wondering how to seal that joint, caulking, weatherstip. What say you all. Walt

I'd probably go with fiberglass tape and epoxy...that's a joint that's going to take a lot of abuse, as you're no doubt aware.

I'm toying with the idea of redoing my tear to get the wheels under the body, that would require wall/floor/frame work.

I'm not terribly concerned about anything special. I would do it just like the rest of the tear. The last coat I put in the body/fender area, where wheel splash occurred, would be spray undercoating. That would seal and protect the wheel well area.

I would also look for some type of fender flair that would protrude maybe one inch, just to neaten it up. The flair would be bought first and the opening made to fit the flair.

What I've got going is, I've mounted the fenders in the floor, but when I install the walls I'll be cutting the walls around the fenders so how do I seal the wall to the fender. David's suggestion of fiberglass and tape is a good one but a lot of work. Also because of the flex I'm concerned about it cracking. Leaving me to wonder if something more flexible would work.

Walt you might use a flexible glue for guttering to seal it. A picture would sure help.

I'll post pics as soon as I get to the shop.

Why do you think it would flex? that would be at the bottom of my concern list if I do mine.... just getting it done would be a hassle...

[Walt M]

Arne, the first concern is, the fact that there is two different materials.( the fender being metal and the walls being wood) the torsion box design I'm going to use for the walls as they attach to the floor. I'll try to upload some pics. I'll be cutting a half circle through the walls and slide the walls over the fender.

I'd use a bunch of construction adhesive in the union between metal and wood. But first and foremost encapsulate the wood with epoxy. After all that, it would get a coating of black plastic roof coating. That's just the way I'd do it.

Steve, I had the construction adhesive (polyurethane)Idea. But I like the idea of impregnating the wood first that would puy my mind at ease. Thanks.

You're welcome Walt,

This advise is from a guy (me) that knows the sound of plywood delaminating while laying in bed awake at night. It sounds like the snap, crackle, pop of rice crispies
