I'm buying some beams for internal attic, floor joist support.
The company changes extra for Red Primer.
Do I need it?
What does it do?
I searched on here and found "BTW, red oxide is not a coating to prevent corrosion. It is a primer only, and rust will get through it if not subsequently painted"
If the above is true, what is the red primer really for in my situation?
What would I need to stop corrosion (if this will be a problem)?
Thanks
