Paintless Dent Removal

hi guys,

wanna know the pros and cons about having matt black paint on my putra...if you don't know what matt black is, it's the same colour as ah fai's cefiro a31.

i'm thinking of using it due to the fact that it'll be cheaper to spray back if any dents or whatsoever happens during motorsports events.

thanks :)

oh and roughly how much would it cost to spray the whole car (in+out)
