I need some help to turn a 4mm post into a 5mm. Would some nail polish layers be enough or should I do something more radical, as cut the post off and replace it with a thicker one?
I know this might sound as a stupid question to most of you, but I'm just a newbie kitbasher, I haven't much spare parts to work on and I'm afraid of messing everything up...
Many thanks to anyone for any advice!
