KBS paint for my frame? Advice needed

[MAC71]

I just had my frame sandblasted and I was going to use a paint that I had used before on a different project that is from Summit Racing that is a two part paint. I tried to order it but apparently Summit, Eastwood and other places can no longer ship these type of paints to Utah. I went to two different local paint shops and asked what they recommended and both stated the KBS rustseal paint. I really wanted to get it painted this weekend as it may be the last warm weekend for the winter and I have extra time off so I got it. Well it takes a while to dry so I was only able to paint two coats on one side and will have to paint the other side tomorrow.
Here is my question, has any one else used the KBS paint and what results did you get. I am now worried because I was reading some stuff online that it fades. I also see there is a different KBS paint called blacktop. Should this go over the rust seal? I am hoping that just two coats of the KBS rustseal will be good for a daily driver as stated by the paint supply shops.
Any advice is appreciated.
