No. 1- will insurance companies approve those parts for repairs, that is the industry bellwether.
2. Auto parts supply chains - will they get approved - not your local auto parts chain stores - there is a whole level of auto parts suppliers that are not on everyone's radar, you need to get on their approved lists. Go to as many body and fender shops in your area and ask if they could provide you with their "suppliers contacts". Then you will need to grunt through their list.
3. Accept resistance to change will be the norm, even if you have a better price-maybe even a better product, you are still an unknown and will only be as good as your last sale until you have built a reputation as having a reliable supply chain program.
I found most of the people in the automotive repair industry to be good hard working people who have little time for conversation, the profits are tight, so just to get them to spend a few minutes of time with you is going to be half the battle. I spent many years in selling to a lot of automotive parts re sellers and used car market. It is a tough industry to get in the door, but once you do - remember how tough it was for you, there is always someone behind you trying to do the same thing.
Good luck
