MLS surface finsih

[scoobydo123]

Had my block surfaced and informed machine shop that need suitable finish for cometic HG. Got it back and was flat but if I took a razor blade at 90 degree angle it had chatter when drawn across surface.



Have hand finished to the below standard there are still some ghost marks from the machine shop but the razor has minimal chatter when drawn across the surface. Do you guys think it is good enough for the MLS. Was also going to use some wellseal. Block is still flat cannot get 1 thou gauge in anywhere.
