I'm going to be buying a new truck soon and wonder if it's worth it to upgrade to a paint coating. It will be Ford's magnetic metallic gray paint. I currently already have the Griot's sealant, wax, rinseless wash, and spray detailer. I've been thinking about going to McKee's 37 but will have to purchase the paint prep, coating, N914, and the spray detailer. Am I going to notice that much of a difference if I make the investment to jump to the McKee's line? Thanks in advance.
