Poly question
 

Can I apply a water based poly over Watco? I want a clear coat and oil based poly tends to run to amber.

Water over poly? One way to make sure you have no interaction is to put a coat of Ultra Blond shellac on the Watco, then top with your water based poly.

Yes if you wait until the Watco is totally cured. At least a month to be
safe.

That depends on how much yellowing is too much. I haven't found a
shellac yet that doesn't leave at least a slight yellowing, although with
some it's very slight. Much less than an oil based finish. If that's
acceptable, you're fine to use it. Just be sure it's de-waxed.

IIRC Watco is oil based?

You "may" already have all the yellow you are going to get.

I've had limited success in this instance by sticking with the Oil-- but using General Finish's Wipe-on Poly instead of a full poly. Especially since the wood already has protection from the Watco, you may be satisfied with a lighter-durability clear coat.

This is not my usual technique, only when I REALLY want to limit the yellowing and still prefer the oil for one reason or another. (Oh, who am I kidding...I always prefer the oil, for all the known reasons!)

Hope that helps.
