As the DSG shift knob retrofit is likely going to take some time, I figured might as well work on deleting the "DSG" engraving in the plate having managed to pry it off intact. I'm fairly certain the piece is all plastic.
The goal is to (i) completely delete the DSG engraving so that it it looks like it was never there whilst (ii) keeping the brushed aluminum finish and equally important (iii) having the finish strong enough to withstand daily usage since this will be the part of the knob most touched.
djm1968 had suggested in a prior thread using JB weld or some other epoxy putty other than Bondo. The former can be worked like clay while the latter tends to swell with moisture suggesting its bad for (iii) above.
I presume the process would be to sand the thing down to remove the existing finish. Applying the putty and sanding that down until you can't even tell there once existed an engraving. Then applying the paint finish.
What grade sand paper for which stage in the process? Possible to get the same brushed aluminum finish? Need clear coating? Where do I get all this stuff?
I've never done anything like this before so any more advice would be greatly appreciated.
