Body Work and Paint Estimate

I know the cost of top shelf materials is outrageous. But I have SPI epoxy primer and that was $200 with the hardner. Their clear and 2k is very reasonably priced as well. I was planning on using all of their products and shopping around for the base. I have already confirmed that PPG and TCP global base is compatible with their primer and clear.

He won't use my products though, he wants everything to be from the same line, which is understandable. What really struck me was his process. He was worried about skim coating the quarters (due to the filler possibly cracking) that told me he probably doesn't know what he is doing on this type of work, also he said he would only do one round of blocking with the 2k. Which makes me feel like he wants to do the minimal amount of work. (He is a collision guy by trade)

I just didn't feel confident that my $6-8k would get me very much in body work. Especially with the cost of the materials he is probably going to use.

I am going to try and get a few more quotes and will probably end up doing it myself, like originally planned. I appreciate everyones support.
Never used the stuff myself, but have heard several say their clear stays soft for extended periods and can be somewhat delicate.
