I bought this as replacement for the broken assist handle in the post above:

I'll spray it with some plastdip/grip, or slip a section of shrink tubing over it and stipple(look it up) the coach side of the shrink tube using a soldering iron, for a good grip.

The new betterer bar is $10 shipped.

I'm going to suggest this as a preemptive fix for what will be a STARTLING failure.
