Alright, so i'm doing some body work at the moment..
There is a lot of humidity blisters all over the car, so a lot of it is going to have to go back to metal.
I have just started using 80grit on the door, also combined with paint stripper to go back to metal. 25% of the door is metal.
There are a few scratches in the metal though, is that from sanding to deep in the metal with 80 the whole time?
Should I have used something like 180 or 220 when i started to see metal coming through?
I have heard about people getting waves in the paint, I would like to aviod that... What is the best thing to do from here?
I'll try and post a photo tomorow.

Is it possible to damage metal from oversanding it ?

you can warp the metal with to much heat by oversanding...

if your going to sand down to the metal..it will leave scratched...just d.a. it with a softer grit paper then pimer with a high build primer...epoxy is tha best
