I've been following this post, and have to agree with MJ. I used the SikaFlex 221 for all the trim on mine (aluminum) and have been very pleased. It adheres well to the aluminum, trims nicely, dries fast, and as yet, shown no tendency to separate from the aluminum. As an added plus, after it dries and hardens (it always stays flexible like a hard silicone), it can be sanded, which I have done, and they say it can be painted. I see no reason whey it would exhibit the same qualities attaching to wood.
As to the "SF" that Steve added, I have no experience with it, but if I read correctly and it is an "odor" issue (offgassing), I really didn't detect any appreciable odor from the normal 221 when applying, and none after it had dried. I'm sure they charge more for each letter they add, but for me, it wasn't worth investigating further.
I give the product high marks.
Still graced with two eyes and ten fingers (due in no small part to luck!).
Just when you think a problem is solved, an uglier result replaces it.
