There's alot of BS in paint brand marketing, here's the deal every vendor has a premium brand and then a generic brand of the premium, but when they go into the mixing room, it all the same base and tints, meaning it's the same stuff, the premium just cost more, this is why professional body shops almost always use the generic brands. Red is alway going to be the most expensive pigment, been that way forever fiquire a extra $100 bucks at minimum for red over other colors. Most paint store also have what they call a overall economy paint line, you will not have a million color choices , but most the colors we would use will be included in this deal, then there are now alot of online piant stores that offer even deeper discounts. The big problem with the rustoleum paint job is that it is not automotive apint, it way softer than automotive paint and it will not stand up to UV rays over time, and remember you only hear the sucess stories online with rustoleum paint jobs, you never hear about all the nightmares. Paiting your pride and joy is a big deal, so piant is not a palce to skimp, this doesn't mean you have to break the paint, car paint is for cars, and rustoleum is for swing set or rod iron fence, it not for your car.
There's a sign in a business that I frequent that says it all for me.
" the bad taste of poor quailty lingers long after the joy of a cheap price has vanished"
