Frame Prep - Under Coat

[strikk]

Hey guys,

My 98 is showing its age from Maine/Massachusetts winters. I'm looking to get the frame cleaned up as best as possible to keep this guy alive for the future.

When it comes to prepping for undercoat, are you guys directly applying the stuff or shooting primer down first?

Ive just been trying to sand the rust off best as i can then just spray it with the undercoat

Depending on the undercoat you use, some dont need a primer but some bond better with a primer

Not to derail another thread but where abouts in Maine are ya from??

ive been using a chassis paint, just clean the rust off, and paint it right on the metal, seems to be holding up pretty nice

and to answer the op, I'd sand/grind as best I could and just undercoat over it!

Excellent, looks like i'm all set to get down to business as soon as the weather warms up again.
I don't think this thing was ever garaged, or washed - runs great though for 140k

Thanks a lot Draggin95, I can't find many bad reviews of the rust seal product.
Following your advice, I've got a quart coming to my door step.

Now if only I could get some warm weather
