Quick and Dirty rust repair / stopping the spread?
Hey guys,
My new car comes home next week, and I know it has some minor surface rust in a few areas... I plan on fully stripping the interior, gutting the car, and repainting it (POR-15), but I don't plan on doing it until later this summer...
So I'm wondering about what to do to prevent the spread of rust until I get a chance to work on it thoroughly. What I was planning was this:
-Wire brush the rust till its all bare metal
-Rust paint or etching primer? (or something else I can buy at Canadian tire/autoparts store, before I make my huge POR-15 order...)
Any holes found (fingers crossed) will get all rust removed, and painted inside and out with (primer or rust paint?)
Any suggestions to improve on this? ...is this what I should be doing... the car is surprisingly clean, and I'd like to keep it that way
Thanks in advance,
Matt

The Por-15 needs the rust to work, if you cover it up now, that covering will need to be removed. By the time you remove that covering, the rust wil be nearly gone too. Save yourself the extra time and trouble and use the Por-15 now, at least on the worst spots.

Any surface rust can be sanded off. As long as it isn't through the metal than you should be good. Just make sure get every little bit, it spreads like cancer. I learned that the hardway.

...POR-15 with the surface prep is supposed to work as well as it works on rust (according to the website).
Now, I'm gonna go look for some POR-15, but assuming I can't find it before next week, what would you guys recommend?
Oh, and how is a wire brush going to compare to sandblasting? (ie. is sandblasting going to take more rust off?) (I know it'll be significantly faster... but I have time.. )
Thanks!

Sandblasting can remove all of the rust, except what is in between the body seams. When the rust is gone, there is no need for the POR-15, use an etching primer, topcoat and undercoat. If you clean out the seams, prime coat, then caulk the seams before the topcoat.

...just want to kill the rust as much as possible...
Thanks

I think the POR15 site sez you can STILL use the POR rust coat even if the rust is mostly taken away - POR sells an etcher product to give the POR15 something to grip onto. I would STILL use the POR15 coating even if the metal is all polished up (but etched). it creats a really bullet-proof finish. I don't think a primer will STOP rust under it from continuing, whereas POR15 (and other similar products) actually bond to the rust and convert it. With a primer-for-now solution you'd need to remove ALL the rust first - and for all that work, you might as well use the POR to begin with-
