2005 ES330 Cracked bumper cover under fog light. Replacement very expensive Any recommendations on type of product to use for repair of damage. Body repair shop won't touch it because of propensity to crack again.

proper way

take off bumper, rivet it from the back with a piece of sheet metal, fill in crack with bumper repair putty, sand down, clean up, do a blow in to match colour and hen add clear

if your in the toronto area, i can direct you to a shop that can do it

or leave bumper on and clean area to be repaired and use epoxy and give it a day to dry and then use bondo, then sand, primer and paint.
