Protecting new panels

[minibm]

Hi after a bit of advice,

I have a classic mini which I started doing a minor restoration on (rear panel , valance boot floor etc) and unfortunately lost interest in but want to now make a start on again.

Now my nice new panels (just with the black protective coating) have got bits of surface rust coming through, I did put some primer on the welded parts which has helped a little.

Now my plan is to rub back surface rust, possibly rust converter then put some new primer on however is there anything better I can use rather than just regular primer? I'm talking something that can be brushed on just over the affected areas (once rust is removed) as I still have the rear subframe to sort and small amount of welding so realistically car will not be painted for another 6 months,

Thanks in advance

You'll need something more than primer as it's porous.

2k Epoxy primer is what you need.You can buy it in aerosol

Just to add, the rest of the car was painted in cellulose a few years ago and will probably going that path again, obviously anything I put on now will be rubbed down but also don't know if there's anything to avoid with reaction etc

The epoxy will help you the most. Also what kind of welded parts are you talking about? Was there some welding work done to it before?

On project binky they sprayed everything with zinc loaded Upol Weld Through Primer

They left most of the metal that way for seven years and it hasn't rusted at all.
I suspect the zinc is the magic part, doesn't matter if the primer is porous, the zinc sacrifices itself and the metal stays clean.

It's also perfect when you pan to weld it as it's weld through so you wont need to rub it down first.
