Edge finished the last few parts. Dimpled all holes in the skeleton with the squeezer. Cleaned all parts with acetone. I used Stewart systems EKOetch E675 1 to 1 as called for. Primed with EKO Prime. I had a rack made with some 2x3s and chicken wire set up on saw horses in carport. Seemed to work well. I had tried engraving part numbers but they were mostly covered over by the primer
