Paint can

[irishtrek]

My sister bought a paint can from a craft store today and asked me if it could be roughed up a bit with sand paper. the can is a quart size with lid.
I never heard of using sand paper on bare metal. Any way I told her to use a primer instead.

Yeah, sure you can. They block sand cars all the time.

Now as to why she wants it roughed up....
