Default Firewall rust

You know the problem: where steel meets aluminum. I have a bit of rust in the corners working from the inside out on a 1972 series. I'm wondering what people do to stop it.

Should it down a bit and put on some POR 15 or other rust-proof paint? I'm just afraid that unless I get rid of all the rust, it will keep spreading. And if I get rid of all the rust I will have holes in my floor. If that's the best option, how would you patch the holes?

Thanks in advance. I just bought a new rover and am a little worried about keeping it nice.

according to how the rust is, cut a little distance from the rust , and re place with new metal , this will prevent the old affected area from spreading to the new , and use mig welding if you could , not acetylene ..

Yeah, that sounds about right. Only problem is I don't weld. I guess I'll find someone who does. Thanks

Technology has come a long way in the area of adhesives. I have heard a lot of good things about replacing rusted out panels using an epoxy to 'glue in' replacement panels or patches. it has the added benefit of not heating up the metal so it will cut down on the distortion from welding in a replacement patch, and the adding of oxygen to the area from welding. I have seen information about constructing cabs for earth moving equipment using epoxy to hold the non-supporting components in place.

The down side is the equipment for applying the epoxy is expensive and probably a deal breaker if you only have a few spots to deal with.

JMVW57,

is correct about the use of epoxy's these days, many parts including door skins and roof panels are only epoxied theses day. it may be a viable option if you have no welding experience.
