I didn't use any special lube preparation for the honing of the chassis tubes, just ordinary engine type oil, but feel free to experiment! After the honing operation, I cleaned out the residue and then thoroughly lubed the chassis tube using a greased mop/sponge. Don't forget to grease the sleeving tube, too. Slightly chamfer the end of each of the sleeving tubes to facilitate its passage. Chalk mark the sleeving tubes along their length so that you can determine how much has been driven in. If the sleeving op stops a bit short of the forward end of the chassis tubes, this is of little consequence (provided you've reached the area of the front spring) as you are endeavouring to strengthen the length of tube between the front and rear suspension mounts.
When you've driven the sleeving tube in as far as you can, simply cut off the remainder protruding from the chassis tubes and weld a new cap over each rear end.
