Hello, I've got 35 yrs in the BodyShop business, I'm the Manager of a busy luxury import Dealership Bodyshop here in Ohio.
I've seen the ole' "I'll pay for it myself" maybe 100 times, only worked out as it should once that I can remember. So I'd get the $ before starting the Repairs, or you will probably be paying for it yourself. Please Keep us informed and let us know how it turns out.
FYI we don't use 'flex agent' additive too much anymore, the Catalyzed Base-coat & Urethane Clear-coat finishes are Very tough, provide great flexibility, adhesion & amazing resistance to cracking. In my opinion, equal to the Factory finish.
It should be mentioned that the quality of the primer that comes on the part is important too. Thats not a concern if you are using genuine factory parts, and something to be carefull of on aftermarket parts. Aftermarket parts are not always bad. but sometimes they can be downright junk! The important thing is to have a repair man / shop that knows the difference.
When Chosing a shop, one good idea is to look for a shop that uses Name brand paints. Those include PPG - Dupont - Nexa Auto Color - Speis heckler- Glassutt (sp?) among others.
