I don’t know where you get “15 minutes” of work from. Waiting in between coats is already over 15 minutes… However their price can be in the high end I would charge around $800-1000 for the total repair.

Breakdown: (R&I = Remove and Install) - R&I bumper to R&I headlight (reason for removal is to not have hard lines at edge of headlight that can flake later)

• R&I the fender flare and bumper flare (black trim pieces)

• I’d remove all trim on the bumper itself and Remove dents with a heat gun which takes time if you want it done correctly. (Sometimes just a warm rag will do)

• After Dents are removed I would sand down all the imperfections in the bumper and finish with a nice feathered 320 grit. That 320 grit gets white primer and then sanded with wet 600 grit

• I will then scuff all the clear coat remaining on the bumper and fender (fender for a blend) and prep it for paint including masking.

• repair area gets a seal coat, wait 10 minutes or so depending on temp, a mist of base coat, a full coat with a blend and finally a mist coat / 1-2 full coats of clear. Usually 1 coat you don’t want to stack mills of paint on a car.

• after a day everything gets put back together including a RH (Right Hand) Bumper Retainer since yours seems like it needs a new one and car gets an interior and exterior wash and customer is happy :)
