Summary for polishing stainless on semi trailer Discussion
Polishing stainless on semi trailer mirror finish is the core question here: Wayne, an aluminum polisher, asks what grit sequence to use on stainless frame parts around trailer doors so he can remove grain and reach a true mirror finish without being too aggressive. Simon Dupay replies with a step-by-step progression: start with a fine-grit emery cloth used across the grain, then move through 320, 400, 600, 800, and 1500 grit sandpaper. After sanding, he recommends buffing with emery cake on a sisal wheel, then using a stiff wheel with stainless compound, and finishing with chrome rouge on a soft wheel. The advice is practical and emphasizes gradual refinement rather than heavy cutting. No one else offers a conflicting method in the excerpt, so Simon’s sequence is the only detailed answer provided.
Q. I’m looking for some one that can help me with the steps I need to polish the back end (stainless frame parts) on a semi trailer that enclose the doors. I’m a Aluminum polisher for Big Trucks and have an inquiry to polish the back and both sides that enclose the door. The stainless has a lot of grain. What grit sandpaper would I start at and finish at. Plus the surface must be a mirror finish. I have done a little of this before, But I didn’t want to be too aggressive. Last time it looked OK but could have been better. Any help would be great.
