Matching colour is the hard part: the manufacturer colour code on the vehicle's compliance plate is the starting point, but paint fades and the code alone does not guarantee a match.
Aerosol and brush-applied products are listed separately. Aerosol gives a smoother finish on large areas; brush and pen applicators are better for stone chips where masking would be impractical.
Primer choice depends on the substrate. Bare steel, galvanised steel, aluminium and plastic each need a different primer, and using the wrong one produces adhesion failure that shows up months later as peeling.
These products are hazardous for transport and ship by ground only. They cannot be returned once opened, and they should not be stored where they can freeze.
