Meguiar's users - Which product do you use?

[Simon Barden]

It's only really an issue for refinishing. It's the same deal in an automotive setting. Silicone can be annoying, but it's not a boogey man, you just need to be diligent in prep.

Best to avoid it if at all possible. If you are making guitars for other people, you can't assume they'll know anything about silicone or want it on their finish. For guitars that you are never passing on, then it's up to you. But certainly for production guitars, there's no need to use it at all.
