All my reading/exploring of the forum convinces me that butyl tape is the sealant of choice for jobs like replacing/resealing windows
, vents, etc. I've started using the Lexel sealant for sealing around rivets when replacing them. I'm gonna be re-sealing & replacing windows
, vents, access doors, & such on my 84 Scamp
& 76 Trillium
My question about the butyl tape is what is the difference between butyl tape & the gray 'putty tape' I've been using for years on my RVs? I still have a partial roll of the putty tape 3/4" wide, about 1/8" thick with a sorta 'crinkley' waxed paper separating the coils of tape on the roll. Looked at some butyl tape (Dicor brand I think?) at local RV supply place & it looked identical to what I have. Felt the same also,
Years ago I bought a small roll of butyl rubber tape that was completely different; it was white, very sticky & adhered to every surface it came in contact with. Used it to seal a roof vent & when I had to replace the vent, thought I'd never get the residue of the stuff off.
Searching the www I also see a great disparity in price for what appears to be identical rolls of butyl tape, some even from the same dealers? Also see it in gray/grey, off white, black, etc. I want to use quality products & have no problem paying the 'going rate' for such but, don't want to spend money unnecessarily either... Anyone have some good advice on solving my dilemma...
If there's a difference in what I've been using & 'real' butyl tape, what is the difference & how do I tell?
