I didn't want swarf muckin up my white stones.
The 10k cracked up pre sealing , I have a feeling that had I have sealed it from new it would never have cracked up.
There is no need to seal synthetics really I just like to be extra
Whoa. Those are some nice synths there, good buddy. And even nicer nats, I'm sure.
How long have the light-colored, fine synths been sealed? If the issue of mold hadn't occured to you before, I would assume it hasn't been a problem. That's no guarantee for the future, sure, but still...
I am confused; if the 10k cracked pre-seal, and you believe that it would not have cracked if you had sealed it from new -- Why feel that sealing is unneeded? Or was the cracking not a functional problem, as others have described; but rather only a minor cosmetic issue which didn't NEED fixing in you estimation?

Finally, what did you use to seal all these up? Was it the vaunted Japanese lacquer I've heard about?
In any case, how did you like whatever sealant it was you used?
And have you subjected it to prolonged (days, weeks) exposure to water, or is only briefly exposed to water when the stones are used and until they dry?
