Duplicolor mirage question

Hi guys,
Sometimes ago, I paint a car using the duplicolor mirage paint and this paint is great. Yesterday, I bought another kit, but when I got home, I saw that they were three color changing spray can. There was no basecoat and no clear, only three differents kind of paint (Step 2)

Do I really need the basecoat included in the kit or I can take another kind of basecoat? And for the clear, can I use a simple duplicolor clear or do I really need the one from the kit?

Thanks for your help.

go buy a can of flat black duplicolor- its the same thing- also just go buy a can of duplicolor clear.

Thanks a lot, already have the clear so I just need a flat black can! :-)
