So I called MRO and they gave me the names of 3 local distributors, Fastenal is one of them. I called Fastenal and I'd have to order a minimum of $200 worth to get it from them. The other two places are closed until Monday but I will be calling them to see if they can get it for me.
If not, Plastikote seems to have okay reviews for their engine paints.
