butyl
 

"butyl tape" has, by far, surpassed anything i have ever worked with. Stays flexible, conforms to irregular surfaces, weather resitant, heat resistant.

A 20 yard roll will set you back about $15.00...

We just pulled the aluminum toe rails off of a 1980 C&C for powder coating and the butyl tape they were bedded with was still flexible and tenacious to say the least. The owner never suffered from a leak.

If you are bedding hardware, this would be my suggestion.

I think this was under my bow plates. Good stuff, to be sure. I can see how it would be good for flat surfaces. Where can one buy this?

My compound of choice is the 3m 101. This has very little bond (read: glue) but is at all times very flexible and very easy to work with. As noted elsewhere, use a ton of it and make sure it squeezes out everywhere. I will say though that the best stuff to clean it by far is the 3m adhesive remover. Not only does this clean up nicely but it will not at all effect your gel coat. I hate 5200 with a passion - try the 4000 if you have to have some sort of glue. It doesn't stick as tenaciously as the 5200 but it seems to bond to a wider variety of materials than the 5200 does.

Hi Mike,
I got butyl tape, for toe rail rebedding, from a RV service shop. They had many sizes and can order if they don't have what you're looking for. Another plus, you can store it a long time and it's still good.

Cheers, Russ

Any RV Service store...if you do not have one close by, McMaster-Carr has it...they are on the web and I have never had any issues with their mail/web orders.
