Stainless Steel Finishing System — Weld Leveling to Final Finish in 3 Easy Steps
Recommended Starting Points
Work Hint: Use the finest grade of abrasive that gets the job done; finer
grind lines are easier to remove. Align the grind line scratches with the grain
line direction of the original stock. Perpendicular scratches are more difficult
to blend; parallel scratches blend easily during finishing. Use a 7" dia. black
ribbed faceplate to level the weld quickly and leave fine grind lines.
