Product review (4 stars): Good product, but you've got to be careful!
Prep is key!  I used a drimmel to sand down the rusty places on my dishwasher rack before I even opened the bottle.
Kept acetone (nail polish remover) handy throughout the "painting" and made sure I kept the top of the bottle clean throughout...this allows the bottle to be closed AND REOPENED...this stuff dries quickly!

On those horizontal places that were too thin after sanding to hold up, I "glued" a cap (that had been cut to go around the wire)  using the UG as both glue and "top coat".  After several weeks of use in my dishwasher, there's only 1 place that needs a touchup...and once that's done, I don't expect to need it again.  I'll be in the market for a new dishwasher by that time.  Uber Goop has given me lot's of time before I need to start looking!  Well worth the price and the effort.  Just have to plan your strategy (bottom first, let dry, flip to work on top so that the drips go toward the underside).
