I know I've seen it before but I can't find it, sorry for asking again.

I am getting ready to start filling and painting my body and was considering using a zip wheel to remove the rust instead of getting media blasted. The problem is I won't be able to get it all on the underside or a lot of the interior. There isn't really any flaking rust but I was wondering if I can spray POR15 over the rust and then hit it with my Self etching primer, primer sealer and filler, then paint? I've painted a bunch before but I really don't know what I'm doing, I just do what I'm told.

Any other ideas or should I just blast it. My friend has a sandblasting truck and said he can use a really fine grade of sand that's like a powder or I might ask him for one of the other alternatives. Problem there is transport somewhere to do it and once I'm there how to get under it.

Lots more questions to come,

Thanks,
Sean
