Rust repair

[Bossjoe]

Hello, I'm restoring a 1968 250 SL. It has a lot of rust. The frame is in pretty good shape. There is rust around the wheel wells and rocker panels. The worst is by the firewall behind the accelerator pedal (It's a RHD). I'm attaching a picture. The rust is clean through. So, do I cut out and weld in new metal panels, or use a POR-type repair?

Thanks!

Bossjoe,
Don’t waste you time and money with minor patching.... cut and weld new floor panels.

POR is only for pitted and surface type of rust.   This needs welding.

What they said, plus: dig deep and hope there's not a LOT more hiding in dark corners. And take it from someone who is currently restoring a seventies Italian car, if you have the facilities, learn how to do it and do it yourself (metalworking, welding and such). It's tremendous fun, rewarding and affordable (as opposed to the $20-50K to have it all done). Three excellent sources on Youtube are Fitzee's Fabrications (Newfoundland), Lakeside Autobody (US someplace) and Trev's Blog (UK). They teach you all you need to know.

To follow up on Cees' recommendation, if you find you do not have a passion for it, don't go any further. You will only screw it up. Repairing a rusted car can turn into a very deep rabbit hole.

Here is a little taste of what you could be in for.
