I assume they are painting it with guns. I would find out from them in the event you scrath something during a needed repair down the road, what products work best to match up if a scrath occurs.
You might think I am crazy, but THE BEST body shop down here for custom shoots often uses Krylon semi flat out of the can. For whatever reason, Krylon matches down the road in a needed touch up. It has go to be a QC process they use.
I had them shoot my Ford. They shot the engine compartment with Kryon semi flat in a can. Sho enuf, I scratched the inner fender well. I taped everything off, sanded the area, re shot the Krylon can and you cannot tell I ever nicked her up.
This car does very well in shows, so she is a keeper. I also won the Ford Fun Weekend Best of Show with her first time out and Best Paint the following year , as they won't give out Best of Show years in a row. That is a serious show, if you have never been to it. Ford employees from around the country actually judge the weekend event. So Krylon works well - trust me on this one. I have a ton of money in this car and I sure am glad he told me that cause I am always doing something to the car. It's a Fird - remember!
They might think you are crazy asking them that, but it works for me. The owner of the shop consistently gets top 5 PPG awards years running, so they know what they are doing.
Good luck with that!
