So I have been wanting to make some engravings filled with liquid acrylic. The first attempt was with untreated wood and the acrylic bled into the grain.
So after this i glued 2 boards together and coated them with sanding sealer.
After engraving i sanded it (the scorch marks away from the edges mainly) and applied another coat of sanding sealer.
Then i filled the engraves with liquid acrylic mixed with different colors of pigment using a syringe. Then sanded and applied a layer of clear coat.
Then let it dry and sanded again using 400 grit sandpaper and applied another layer of clear coat, its drying now.
