First, let me say that I'm still a relative newbie at model building...which leads me to the reason for this post...
I've just primed a model that I'm building. I've modified the heck out of this kit and while I thought I was being careful to remove telltale scratches, but my coat of primer has shown how wrong I was! Now, I need to fix the scratches (and in someplaces there are lots). I've also noticed a couple of seams that need to be touched up. I've done some searching on the forums and have ideas on how to fix this (i.e., wet sanding with finer grits). But, I don't want to further mess this up and thought I'd double-check before I jump in feet first:
- Given light scratches, what grit sandpaper should I start with? 320? 400? 600? I get that I should work up and eventually be polishing the plastic.
- I have Flex-i-File's Flex Pads which include a 600 grit and a polisher/finisher. Is that sufficient? Should I use 800 or 1200 grit sandpaper?
- For deeper scratches and the visible seams, can I apply putty over the primer or should I remove the paint (with either paint remover or sanding) and then apply the putty?
Thanks for any insight. I appreciate it.
