i just sanded down my 1992 gt mustang and brought it to the autobody guy to get it painted. when i was sanding it i noticed that there was fine visual cracks in the paint. couldn't feel them buy touch, could see them though, so the body guy said i would probally be able to see them through the new paint. i said apint it anyways because it needs new paint because it is super dull. so what does anyone think? will they show up?
