I'm getting ready to re-install my cylinders ('88 R100RT). In the past I've used very thin coats of Three-Bond and Hylomar for base sealants. My Three-Bond tube is dead (apparently cured in place after the first use), and I've read in my searches that Hylomar is oil-soluable, so I won't be using that product again.
I'll probably go find another tube of Three-Bond, but since I have two days before any bike shops are open again, I thought I'd post this Q:
In addition to Three-Bond, I've seen various recommended sealants, primarily high-temp RTV, including Permatex Ultra Grey. I have a tube of Permatex Ultra Black high temp RTV -- any reason I could not use that instead of the Ultra Grey?
Oh, and while I'm at it, I'll pitch this Q out there: What about no sealant at all?? There's an o-ring about the cylinder base and two about the upper stud oil passages -- is the sealant just belt-and-suspenders or really needed? Putting it another way, what has been the results of not using a sealant in addition to the o-rings? (of course, I mean *actual* experience, not "well, I haven't tried it but I don't think it will work").
Thanks!
