Butyl Tape as a seam sealer?

[Joe Grippo]

Anyone ever use (Glass) Butyl Tape as a seam sealer? Is it paintable? I had a few feet given to me and I want to seal up where my roll bar passes through the firewall. I was planning on getting the 3M seam seal tape I always use but couldn't find it at any of the local parts stores...I can order it and have it tomorrow but I was curious about Butyl Tape?

I can't answer that directly but if you need something to seal for fire penatration into the interior, try looking at the fire stop chaulking used in buildings when they seal penatrations for fire protections. Every hardware store carries it. They even make it in a spray foam with a nozzle, much like the spray foam insulation.

the stuff works great sealing walk-in freezers and coolers to floors (because they can ultimately be removed without damaging the floor); however, the adherence properties aren't that great - and it attracts dust like it's magnetic - so if it lifts, it'll never stick again.

but no, I've never used it as a sealant for a roll cage..... they do make a seam sealer (butyl is an ingrediant), but for the life of me I can't remember its trade name. Comes in a tube, be sure wherever you want to put it - because it's not coming off - and it seals in vibration-prone environments....

I would suggest using an oil based caulk. The clear OSI Quad is thick (won't run and will fill gaps), stays very elastic for a long time, and is paintable once dry. It does not get hard and crack like latex caulks do. Make sure to use the clear; the white isn't as thick.




*edit* I usually shudder when people suggest using home products on their cars - but I really believe in this product and don't know why it wouldn't work well for what the op was asking about.
- keep some mineral spirits handy to smooth things over, and to clean fingers.

I ended up getting the usual 3M strips I have used in the past...Thanks for the replies.

I know the stuff we used was a vulcan rubber compound.... messy, but paintable and flexible for decades
