The recent thread on waxing a saw table and the repeated frantic
warnings there in about the evils of silicone, or is it silicon, I can
never remember which is which, well, no matter, suffice to say it got me
thinking about the stuff and I thought I'd add a little clarification
for the newbies.
Silicon(e) is tenacious stuff and if it did get on your saw table or any
tool for that matter it is not only difficult to get rid of but it will
transfer to any wood passing over the contamination.
In regards to finishes, what happens is that when a finish is applied
over the silicon(e) the stuff leeches into the finish and reduces the
surface tension of the finish in the finish over the contaminated area
causing fish eye. Not a good thing
Now I'm not advocating using anything with silicone and feel it should
not be used as a lubricant in a wood shop. However, when you stop and
think about, it not using a wax because it may contain silicone is
somewhat like the warning not to use steel wool when using water based
finishes. The blanket warnings overlooks the whole story.
Steel wood can be safely used on a water based finish ON and AFTER the
last coat has cured since the water causing rust has evaporated.
Likewise, by the time you get to applying a wax containing silicone to a
finish your finish is on, cured and you are long past the point where
the silicon(e) will cause any problem. Silicon(e) has no adverse effect
on a finished finish.
In other words, with a little care to isolate the wax from getting
spread all over the shop there is absolutely no reason why you can't use
your favorite car wax or other polish, silicon(e) or no, to bring out
the shine and protect your finial finish.
Just a thought, have fun with it.
