A vote for Anchorseal or paraffin. Isn't AS paraffin based?
Latex paint has long been discouraged - water goes through it too fast. Maybe work better with multiple coats?
Oil-based paint is reported to be better. Aluminum paint is also reported to be very good. I don't use any kind of paint.
UC Coatings told me Anchorseal is a paraffin/water emulsion with a surfactant. (Surfactant lowers the surface tension. We use surfactant on the farm when applying liquid weed killer to fields - allows the liquid to coat and stick on the leaves rather than run off.)
I stick with Anchorseal and have great success. HOWEVER, Anchorseal, as it comes, is not useful in my opinion for woodturning blanks - it's too thin. I believe one reason it's thin so it can be applied to log ends at sawmills by spraying. (I used to do that)
I've described before what I always do to make Anchorseal useful to me for preparing and drying wood blanks of all sizes.
- I pour an inch or two in a plastic coffee can
- Leave the lid off for perhaps several days so some of the water evaporates.
- Mix it occasionally to judge the thickness. When "right", put the lid on the can.
- Apply the thickened Anchorseal with a cheap brush. Leave the brush in the can, close the lid till next time.
When a can starts to get low, I sometimes start drying more in 2nd plastic can so it will be ready if I use up the first.
Years ago I bought a 55-gal drum of Anchorseal (about 6$/gal then). It's about time to buy some more, I'm thinking 5 gal this time. I hate to pay the per-gallon retail prices.
For wood with a bad reputation I have used plastic wrap over the wet Anchorseal, but rarely.
