Running board prep

[1930artdeco]

Ok so I need to replace the mats on my running boards. This will unfortunately be done on car so I need to see if I have the step correct.

1) put paper up around painted surfaces
2) remove rust to bare metal
3) prep metal and then use a primer on it
4) paint with either flat or gloss black
5) use gorilla glue
6) attach new mats and trim

Have I left anything off?
