Painted Rubber Bumpers yes.
Painted Chrome Bumpers no.
Just my 2¢
Just put AMD Chrome front and rear on my 70 Go Mango (Dodge version of Vitamin C) Challenger. Less than $500 new for the pair. Tamraz seller on EBay they look good.
Repop Rubber Bumpers from Tommy the Chryco are $850 a piece $1700 a pair then you need to have them painted to match.

Just had 69 Barracuda Bumpers rechromed and they look like jewels!
Never cared for painted metal bumpers but that's just me. To each their own.
If painting the metal bumbers I would at least have the mounting bolts smoothed. No substitute for the real thing though.
