Preparing Painted And Bare Metal For Painting

[JonnyAlpha]

Hi;

I have nearly finished repairs in my boot (replaced the back end and corners, new inner arches etc) I will also be doing the Inside of the Mini and the Underside.

I will be painting with Epoxy Primer and Cellulose Top Coat.

Any new metal and repair panels will be taken down to bare metal and I'll be applying U-POL Fantastic Filler in some areas but what should I do about the areas that still have the original paint on in good condition? I don't want (and can't) to take it all back bare metal so would I be OK just sanding it to give it a key and painting over it with Epoxy?

I have got 320 and 800 grit.

Here's the boot area to give you an idea:

I would just rough it up with 320 but when it comes to paint I'm no expert!

If you can get round those welds on top of the wheel arch with a wire brush it might help.

No fear, the photo was taken before I have started prepping the area for painting, all the welds and bare metal will be cleaned up shiny, keyed with 320 Grit before painting with Epoxy Primer.

I'll then apply filler onto bare metal where needed before painting with Epoxy Primer.

The areas that still have original paint on will be keyed with 320 Grit and painted over with Epoxy Primer.

You have really cracked on with your Mini, Johnny. You certainly put me to shame with what you have achieved in a short time.

I would key with 120-150, 320 is quite fine
