I dont think it will be cheap... they have to knock out the
dents or fill it up with something... and then give your car a new
coat of paint.... if only the doors are affected, then it's of
course cheaper than painting the entire car lah....
Just my personal thoughts... dont really know how they do it.... If
there are really workshops that can remove these dents at a cheap
price, do tell me too.... I have a lot of such dents also...
SIGH....
I have attached a rubber strip across the sides of my cars to
prevent further dents but the strips are ugly...
