not a good idea,the black stuff is a temporary coating you need to paint the entire surface of the new parts.
the hood, fender,whatever should be painted with real paint inside and out.i still don't understand the reasoning on not wanting a bodyshop to do it right and colormatch it.or why the cheapest crap panels were used(dent easily and don't fit correctly) and ghost tried to talk the insurance company into getting
less money?
you got estimates? so has a shop even looked at the truck?the adjusters who write "estimates" don't know what it takes to fix a car,they are there to f&*k the bodyshop and customer into chintzy repairs.bodyshops fight most estimates handed to them because
the insurance companies never want to pay to get it to actual preaccident condition i would be worried about alignment and other issues that a trained eye can spot like mark said.
if its not totalled the deductible should be the same?so why not get some of your premium dollars back to fix as much as you can?
you should only DIY if theres no paint or suspension work involved in my opinion unless you have access to an alignment machine,and mixing station and pigments
i worked at one of the "good" bodyshops and i delt with this all the time,it sounds like you might wind up having to pay for the gap between payment and actual preaccident condition.
i'm glad i have a tough old ranger, i just bounced a deer off my bumper all the way across the road in circles the other night and all you can see is some hair and blood
