Body rust and surface rust and how to remove it?

[Rotary#10]

Im restoring a 90 gtus and it has rust in various locations around the body and on the surface. I'd like to hear what the folks of RRC recommend at how to remove it or neutralize it. I know this car has body damage. I plan on painting this car sometime next month if Junpower isn't busy. And of course getting the damage fixed. I will be helping him with the prep and body work and he does the paint.

What can I do ?

That would be an excellent point if humans were born knowing everything necessary to restore a car. Since we are unfortunately not we have to learn somehow.

As a side note, you're on my idiot list. If you decide to mature in numerous ways I shall remove you from tHe list.

Honestly it depends on various things. If the rust is deeper than surface rust, then you are more than likely going to have to cut out the affected panel, and weld in a new panel. If it's surface rust with no pitting (pitting indicates that the damage is extremely severe and that you will need to sand the metal away or sand/particle blast the area before filling it) then you can get away with a wire brush and removing the surface rust, cleaning the affected area, and finally filling and priming the area with rust conversion primer.

Again, agreed with the exception of the piting. If it's pitted and weakened I'd cut it out and replace it. If it's minor I would sand it all down with a contor DA pad. Hit it with some rust converter and then resand it so that the converter is only in the pits. Prime it with a good epoxy primer and then get into it with the filler/glaze.

Go right ahead. You just lost the repect of a bunch if not 99% of the members here and classified yourself as exactely what your SN is, a little boy.

Can;t believe no one's mentioned it yet but POR15 is a good product if you need to treat rusty spots on the car. Remove as much of the rust as you can, then treat the area with a naval jelly or some other sort of surface prep chemical, and then go over it with POR-15.

I finally got the chance to actually use it on our college's autocross VW GTI build, and the product is amazing, and tough as hell to boot.

EDIT: Now, we only used it for the underbody/ interior and I dont know how smooth you can get it for body panels because we brushed it on.

Naval jelly is useless. Waste of time and good coin. I personally prefer mechanical methods to removing rust.

I can't say anything about POR products be use I've never used them. I will say that out of the pros and old timers that I've ever dealt with, none of them have ever reccomended any of their products for anything. So I take that and with the knowledge that everyone on the internetz thinks its the cats meow lead me to personally believe that POR is nothing more than internetz, noobie nutswinging hype. But that's just an opinion of someone that's never used it, not intends to, buhas never once had it eecomended to me or even heard of it outside the interwebs

Oh yeah, you don't want paint to be "tough as nails" or "thick as hell," it lends itself to chipping and then you're back to square one

[Max777]

But that's exactly what I meant, it is highly chip resistant and durable.

what i should of said is i have repaired a lot of rust damage and i know it can b a prick, so depending on the extent of the damage if ur not sure/confident it could b a good idea 2 have it done professionally, i apologize for my blunt and thaughtless remark
