Thanks for the help guys. So why should I sand carefully u mean so it wont scratch the primer too much?
Should I use a finer grit sand paper? I thought if you wet sand it its better because the water acts as a slight lubricant to make the sanding finer........is this true?
What about getting the hair out?
So If I get the hair out by lightly sanding the primer without going right through it, do i still have to prime afterwards or can I let it set and then paint the main colour later?
Thanks
