I don't want to glue these parts, only seal the joints.I suppose it depends on what you are trying to seal, and why no adhesive properties?
What "grade" would you suggest? I certainly won't get usable advice from the folks in the local hardware store.I'd use butyl. Since it is used in construction it should be world wide. But check the grade. Some are latex-based. filled with fibers, and useless for this purpose.
That is a problem. I've always simply examined it. You can also get it through some chandleries; it is becoming more popular.What "grade" would you suggest? I certainly won't get usable advice from the folks in the local hardware store.
Actually, not true. I just did some testing for Practical Sailor that revealed that some removers do a good enough job that following up with a PU like 3M 4200 is 100% strength. I was surprised myself. I also confirmed that abrasives and solvents do not work.Avoid silicon. It will leave a residue that is difficult to impossible to remove with abrasives and will impair the ability of anything sticking to it.

I have not tried the vinegar, but I routinely use ether/starting fluid remove normal tub and tile grade, and "mechanics" grade silicone and all traces of it...Vinegar, a stiff scrub brush and some elbo grease removes silicone.
