One of the key elements that made paint durable in the past is the lead content. Made paint very hard and therefore difficult to scuff or chip significantly. As for chipping keep in mind that in 1/35 scale a chip/scratch 1/35 of an inch would equal to a 1 inch chip/scratch in 1/1 scale. In my opinion it is usually overdone although it seems to be a trend and many think it looks cool. For me less is more when it comes to chipping. In the end however it’s each individual’s own build and if you like it then hey, go for it.
