chassis paint or powdercoat

[excavator81]

hi all builders just wondering what would be the best solution to finish the chassis

PAINT:what type is hammerite up to it????
:2k / celly / truck paint

POWDERCOAT: if i need to weld after for some reason will it wreck it

are there any other ways of finishing your chassis info much needed as im unsure what is best for my chassis

kind regards Dan the Digger
