Rust Fights Through Primer

[DSC]

Welp, I finally took care of the rust spot on my car. &nbsp;used a razor and cut back the paint around the rust spot to make sure there wasn't rust under the paint...there wasn't any. &nbsp;I applied navaljelly or something like that, left it on for 5minuets and cleaned off. &nbsp;After doing that the rust was totally gone...that stuff ate it clean off leaving bare shiny metal. &nbsp;So I cover the surrounding area and spray my primer on...all is well. &nbsp;Now, a week later, The rust has come through the primer <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/nervous.gif" border="0" valign="absmiddle" alt=':nervous:'>

What went wrong? &nbsp;What should I do now? &nbsp;Do I need more coats of primer after I get rid of the rust this time? &nbsp;

I hate rust! &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/mad.gif" border="0" valign="absmiddle" alt=':angry:'>

i would do a good couple coats of primer to be on the safe side.....

I would take the naval jelly to it, then hit it with a grinder, to get all possible crevices. &nbsp;THEN, hit it with brake cleaner since it won't leave a residue. &nbsp;Take a cotton cloth and wipe it clean after the brake cleaner, and then quickly primer it.

By the way, did you ever get that 10 bucks I sent you for the shifter?

Well, this is a very small section of the side of my car with good paint all around it, so any sort of grinding doesn't sound good to me. &nbsp;However, I'll try everything else, skipping the grinding. &nbsp;Thx for the tips.

heh, yeah I got the $10 like 4 months ago <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'> i thought I sent you a PM...maybe not. &nbsp;I'm bad with those...worse with e-mail.

I agree with the naval jelly and the grinding from above. &nbsp;To me, rust is like "auto body cancer". &nbsp;If you don't take steps to completely remove the rust, it WILL come back.

<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/butbut.gif" border="0" valign="absmiddle" alt=':but:'> Primer is not ment to act as a final top coat. It has NO water proofing properties and will let water, fog, mist and others attack the metal again. Sand or sand blast to bare metal, treat with a rust preventor and prime and paint...

DSC,

When I was 16 I bought my first car...a FIAT! &nbsp;I know ALL about rust!

If you want the rust to disaapear forever, you need to cut out the offending metal and weld a new patch. &nbsp;Rust is like cancer, it never goes away unless it is completely removed. &nbsp;Most rust holes start from the inside out, it's much worse than you think when it finally pokes thru the paint. &nbsp;The inner sheet metel is already damaged.

Naval jelly and other chemical treatments will make it go away temporarily, but I guarantee it will be back, especially if it is humid out. &nbsp;

Sorry to be the bearer of bad news. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/confused.gif" border="0" valign="absmiddle" alt='???'> &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/confused.gif" border="0" valign="absmiddle" alt='???'>

naw, the car got scratched...deep. &nbsp;And it was a small enough scratch that I didn't notice till it started rusting. &nbsp;when I cut away the paint surounding it, it was rust free.
So I think its just surface rust. &nbsp;Keep in mind, its a good cond' 96...just got keyed or something *shrugs*
