Rear fender well rust repair

Well today i decided to grind done the rust and the metal was rotted all the way through.

So fair i completely replaced a door to avoid the rust.....and the repair.

But now i cant really replace this.....I plan on using fiberglass to fill the hole after using rust be gone (or something like that).\

Any suggestions on a fix that doesn't require welding? What have you guys tried?

I mean as far as stopping rust, you have to cut it out. Otherwise, no edge primers/rust converters/rust neutralizers will stop it... it will always come back.

But if you are crafty and daring if you cut out the rust and use duraglass and fibreglass mat/mesh you could remake the part.

It may be more work than its worth.

Bondo holds water, that's why it is considered a body filler, to smooth out contours, rather than fixing rusty holes.

what? youre taking this opportunity to go widebody? good idea bro!

Hella flush or GTFO lol.

But really, welding (despite cost) is the only way to go.

If it's on the rear fender, be sure that it hasn't allow rust/corrosion to spread further up into the strut tower. I'm not sure how similar the rear fenders are between my wagon and the sedans, but for what it's worth: http://legacygt.com/forums/showthrea...is-205615.html

From what I've discovered, rear fender rust is cosmetic til it ain't. Good luck, and here's hoping it's just superficial!

well luckily my neighbor used to repair cars so he is going to teach me and help me out. thanks

This may sound weird but it works great. If you grind out the metal and there's nothing behind it to lay the bondo over you can use that expanding spray foam in a can they sell at Home Depot. Just spray in the hole and let it expand and dry then grind it down below the actual surface about a 1/16" then lay the bondo over. I've done this in the past for a quick fix and it works good but in the end it will come back. GL.
