I’m never polishing anything again, at least nothing as complicated as an RB26 inlet plenum!
I calculated around 40 solid hours to complete, and I didn’t even complete the bottom of it!
- Paint stripped it
- File finished the whole thing, casting marks, letters, deep pits from the sand cast
- Used the above mentioned “fan like” paper sanding drum on the end of a drill, with a small 1” one for between the runners.
- Worked way from 400 600 800 1000 grit. Then went straight to the stitched cotton buffing wheel drill attachment. The finer cutting compound was enough ( I think because I went right up to the 1000 wet and dry)
- Came out really good, I should post some pics up.
I would never ever attempt this again, unless paid an insane amount of money.
Iv heard ppl do a little each night in front of the TV, with it on their lap, but I prefer doing it wet, the paper lasts a lot longer and doesn’t clog.
