Maybe there's actually two up here, Ray. Some of you may be aware that my car got wrecked pretty badly back in Sept. of 2014. In a nutshell, I got four estimates. A well known Corvette fixer from the West end said $10K and he wanted the car for 6 months.
Any shop that wants only X dollars but won't get your car back to you for 6 months is really saying that they won't look at your car for 5 of them .....
Not sure and I don't know the whole process but he said the car needed to have time to completely cure slowly before paint or we risk the chance of spider cracks etc. BS...maybe, I just don't know.
I had not read your post at first David, the only thing I can say is that IM cures their cars under a UV treatment I believe, otherwise the body moves as it cures.
So hence the body shop guy might have been trying to wait but then no UV light treatment means a slow rather than a fast cure... and thus he waits how many weeks, months. I am not sure how important it is for your car body as FG gets old it has to cure by itself I would think.. Alan the watch builder should know more.
Any accident is a frustrating thing.
