Hey guys,
I am lucky that my 68 has only a little bit of rust. But the one spot that is the worst is in the quarter panel right behind the driver side rear wheel. It is rusted through in an area about 3x2". I know that someday it will have to be cut out and patched up but that isnt going to happen for awhile. So my question is... What should I do to slow the rust down for the winter. I dont drive the car much in the rain but it will get wet. And it will never see salted roads or snow but should I coat that rusty area with some of that por-15 or something else just to keep the rust from spreading faster than it already is?

Sorry if this has been answered before on here. Thanks for any thoughts on this. Cheers.

 

POR-15 a dremmel tool with the wire brush it will break off all the lose rust and already destroyed metal.....after that just bondo it up until you can properly fix it.

 

Sounds easy enough. I will get at that this weekend hopefully. Okay this is another noob question... Never used bondo before. Any brand recommendations or tips to keep it simple? thanks USMC, and any others!

 

Just plain old bondo from wal mart, if you intend on fixing it properly in a year or 2..

 

same principle as repairing a hole you punch in the wall. if its just a temp fix i wouldnt worry to much about high quality bondo (if there is such a thing). its just time consuming so dont rush thats the only tip i can give you man.

 

Thanks guys. 'Preciate your willingness to help on this basic one.

Try to find the bondo with fiberglass in it. I've seen it at autozone and advanced auto, I hear it holds up better than regular bondo and paints better.

I'm no expert on body filler but what I think I know is that "plastic" fillers hold moisture. Repairing rust with Bondo could make it worse. Especially if you just primer the bondo because primer absorbs moisture too as it was not intended to be a top coat.
I would repair the area by wire brush/wheel or sand blaster and treat it with something like "extend". Then maybe you could patch the hole with fiberglass. After that you could use Bondo but there are some alternatives like polyester or "all-metal". If it's a temp fix maybe this is all over kill but I would paint it even if it's just a rattle can to seal it from moisture.

 

is there a gaping hole or bubbling paint?either way,chances are that it won't grow that much in a couple of years, and you can cut it out then. or, if you can weld, cut it out and weld in a patch now!!! both the patch and bondo need to be painted over. and the only problem with the bondo is that water tends to get trapped in it, sit and casue the rust to worsen, then the bondo falls out and you do it all over again. it took that car 40 years to get to that point, its not going to rust any faster now that you own it.

 

if it is a temp fix there is no need to go all out on this thing, time & moisture is the killer over winter....i dont think you ahve to worry about it.
+1 to tarafied on the top coat.
