Might try SS to give even absorption.

[charlie knighton]

ok.......what is SS, how do you mix it , does it work with acrylic and air brush?????? any tips

Charlie, yoou might try something similar to what I did on a vase. I applied a layer of Minwax Wood Filler on the interior surface and quickly followed up by creating a grooved scratch pattern using carvers hand rasps while the piece is slowly rotating on the lathe. The wood filler dries fairly rapidly so you need to advance in steps rather than trying to do it all at once. Next, I sprayed stone texture spray paint on the interior. This creates a look similar to a vase that is similar to one made on a potter's wheel. The exterior can be done as you wish. One option would be to sand it smooth, seal the wood and then use the stone texture spray paint. Designs can be painted on the exterior as a final touch.

As far as tearout goes, it might be the wood or it could be a dull tool or it might be chatter.

ss could be sanding sealer?????????????

If I'm not mistaken acrylic paint is usually thinned with water not dna. Build it up in layers and sand it back til you get a smooth surface.

I have used white and black gesso as a base on turnings. I thinned mine but unthinned I believe it would have covered your surface defects. I also burnish it to get a smoother surface. It remains paintable. I have never shot thinned acrylic through my airbrushes but acrylics work fine on gesso so I don't think the delivery method would make much difference. If I remember right, gesso is crystalline clay particles suspended in an acrylic base. Too lazy to go out an read the label on my jars.
