How many cans to paint a car?

[rtha6551]

A lot. Spray cans are SUCH a expensive and wasteful way to do it.

I can get the cans for £4.95 for 600ml, was told by someone 10 cans should do it but asking here for more advice

Considered using a roller too, does this tend to be cheaper?

If youre ruining it anyway, why not just roller it?

Tbh I am ruining it, it's a sigma but the paint is fcuked and someone has tried fixing it with a rattle can and over sprayed everything
