Reason I ask is because the Zinc Primer Epoxy is listed in their website as a Indoor Use Epoxies and I need a primer for some scooter rims im planning to do. I read about the different Primers that tiger has and was a little concerned about the 3 types they have.

1301 Series 69 - 69/90350 Zinc Rich Primer for steel

1302 Series 69 - 60/70000 Dry Protector Primer steel/aluminum

1303 Series 09 - 09/73841 Zinc Free OGF Primer steel/aluminum

What are the differences on these and is Caswells fin for motorcycle rims?

Or at this point is primer really necessary?
