Water Based Paint - Improving Durability??

[6C4GTS]

Its almost two years since my last front bumper respray and the numerous stone chips and general road rash mean it needs done again.

I'm pretty sure my usual bodyshop uses water based paint (does everyone?) which do not seem to be very durable to chips etc.

Is there an option for applying an extra lacquer coat for added durability or is the only option to either add a protectant film or keep getting resprayed when the chips get too bad?

TIA

Thanks - is there any value in asking for an additional (2nd) application of clear coat or is there an issue with this?

So the advice then is to invest in a good clear top coat - and then get a good sealant and wax on top - yes?
