Bare metal panel preparation - Advice Please

[Chris598]

Hi, I've recently restarted restoring a TR7V8, but have some question over the validity of the project bearing in mind the state of the bodywork. I'm ok with cutting out & welding in new floor panels, sills etc, but unsure of the actual exterior bodywork prep.

Below is a close up of the passenger door. This door had a new skin 10yrs ago but sat in a damp lockup ever since & has loads of surface rust through the black transport paint. I've stripped it to bare metal using "clean & strip" disc and applied Jenolite (I'm on my last litre, switching to POR Metal ready from then on). My next step was to prime it with Bonda Rust Primer to give it some protection whilst I finish welding the bodywork etc.
However, I am a little concerned about the amount of pitting in the metal which is similar across the whole car.

Can I treat this as above, or is something else required?

That sort of corrosion is normal for "new old stock" panels too. So long as the rust hasn't made it all the way through the panel it's nothing to worry about. I normally remove it by shotblasting and then apply a little filler before primer, but the Jenolite should be OK too.

It'll be sealed by paint so won't be able to rust any more, so the main thing is getting the surface level.

Thanks Malcolm, I'm going to look onto getting the shell shot blasted after i've done all the repair work. I'd do it myself but only have a 6cfm 110psi 50ltr compressor, barely enough to run a DA sander never mind a blaster.

I only shot blast because I have the equipment, but it's a fantastic way of getting rid of the stuff in crooks and crannies. Your prep in the photo looks fine - bit of filler would get that right.
