Durabak spray on frame but what about inside frame?

[alex e]

After painting my frame with 1 step, I'm thinking I'm gonna spray Durabak liner on it but what about the inside of the frame rails? Sorta rusty in there but not pitted or anything bad. Should I 1-Step the inside as well then Durabak? I have a spray can of 1 Step for touch ups, but the brush on is heavier and requires less coats....

Thoughts?

Undercoating Gun (BS/A WB)

There are purpose built guns for undercoating with wands that should have no prob with duraguard but I am not sure how effective cleaning it would be afterwards ---that stuff sticks like glue

also you could consider POR 15 or WAXOYL or a variety of other products for those areas

If i could not sand it down I would high pressure spray it and clean it out good with TSP then maybe a rust converter prior to coating it

I would not put Durabak on the frame, it may peel off. I would stick to POR15 or equal. Also why would you put Durabak on it? Everything will stick to it. Also Durabak cost more than POR 15.
