Al Serra Buick GMC

Overall, I like the truck that I purchased. All the processes for purchase were expedited and the staff was very professional. The only problem that I have is the existing damage to the paint job that I didn't see until I got the vehicle home. I brought the vehicle back to have it touched up and I am not totally satisfied with the work that was done. It looks as if there is the potential for corrosion or rusting because there is still exposed missing paint. I would rate the experience as better if I could get that one issue resolved. Can someone please help me resolve this issue?
