I am going to fit a new front wing to my daughters astra. To ensure a good fit it will be a genuine Vauxhall part and I propose to paint it myself using aerosols. These will be obtained from the Vauxhall parts department.
Because these aerosols are only 150mL, and quite costly, I will need quite a few, therefore I am proposing to use larger size, and I hope cheaper, cans from "Halfords" for thefirst few coats.
My question is without knowing what type of paint both types of can are filled with will there be any reaction between them once applied.
I am also going to use large cans of primer from "Halfords" and will leave the inner surface of the wing in primer.
Can anyone find fault with my approach or do you think it is okay.
