Bob, I have about 3 hours on the one side, with maybe another 30 min left.
Used 2000 wet to knock off the big stuff, then 3M Finesse it II, then 3M Perfect it. I use Wenols for any tar I find.
I have polished these before. The first time getting all the surface carbon off took a long time...
I had a sidepipe break the welds at the collector flange, so I pulled them both and re-welded the flange on one, and cleaned up all the welds.
So today I started polishing them (much easier when they are off)
The first pic shows what I started with, the second is in process, and the last they...
I need to replace my stock Michelin's on my F250 PS, the Michelins have been fine except for wet driving.
The Nittos for my truck show two numbers:
LT275/65R20 E 126/123Q
LT275/60R20 E 123/120Q
Do you know what the difference is between them?
