Butyl tape????

yorklyn · Post by **yorklyn** » Tue Jun 12, 2012 10:15 pm

Anyone use Butyl tape instead of caulk to rebed hardware??? Found some good info online and was thinking about trying it on the bowrail and window frame. Seems to remain flexiable forever and have more elongation than caulk. Any first hand experience???

Thanks

Use it weekly. Ford is big on it since they have bolt in 1/4 glass and use it alot on cargo van glass "fixed glass". Just buy the good stuff. Ours is 3M. I havent seen any leak issues in the past few years. Run your tape and over lap 1/8 inch. Hardware as far as screws and bolts to close the joint? I am going to do that too. Its alot less messy than liquid sealants and should serve the same purpose, cheaper... IMO

sorry Im getting the feeling that Im wrong about 3M. I will double check tomoro and let you know. I have been using it for some time now.. Ill post back the name part #. I think its 3M but the package in my mind is telling me different. Still good stuff with no come backs at the shop!

No first hand experience, but know a couple of snailors (spelling on purpose) who have used it to rebed hatches and portholes, and they swear by it.

whats a snailor? sorry had to ask Capt!

Its good stuff on car windows is all I can say, tight and no mess at all. thinking you can pinch off a bit and run a bolt or screw in, seal it tight. IMO

Not sure I would use it on rail stanchions.... as the potential lift force would concern me compared to a window install where that tends not to be likely.
I have used it to bed glass in hatches and the long side plastic windows on a Bayliner 2550 back in the '80's without any adverse effect... Note northern climate with freezing winters also.

+1 wouldnt use it where and regular pressure would be applied. Just bedding glass or maybe set screws on the rub rails, but im leary about that. this stuff is very flexible though. Im just thinking on a screw or bolt insert you should be ok as a sealant.

Thanks guys! I have never used it before but I came across this article which seemed to make sense:

Just thought I would see what everyone else thought of it.

keep in mind that the bow rails do see some force from time to time.

Could be some flexing at the base?

Having read the article it certainly seems to me that butyl would work on deck hardware.
My only question is.... is it the butyl or the countersink that produces the good results.
I am inclined to think the countersink is also a key rather than just the butyl vs sealant change..... though butyl staying pliable for years may well deserve some consideration.
I have seen signs that my F32 windshield frame is bedded on butyl that is still pliable after 34 yrs.

I just discovered the stuff and I love it!!!!

I agree you wouldnt want to use it on items that take force as the stuff does oozzze out for a while.
