My car's at the shop right now getting full rust repair, body work and paint. I don't know if I fully trust the shop at this point, but I don't have any specific incidents that I attribute this to, just a vague uneasiness. My question is, is there anything I should be on the lookout for as far as shortcuts they may take, or things that they could do, or neglect to do, that might result in problems?

I am not a body and paint guy, this is my very first full resto, and as I said, I don't KNOW if I trust them. They came highly recommended, and I've seen some of their work, which is fantastic...I'm just curious if there is anything I should specifically be on the lookout for that will tell me whether they are doing things the right way or the wrong way. See attached picture to get an idea of how things are going. Any advice would be most appreciated. Thanks!
