I want to start the paint work on my mini. There are a number of areas which need looking at but no major rusty bits. A couple of areas where the previous owner has just painted over cracked and flaked paint and I want to remove it back to bare metal, fill, smooth and repaint.

What is the best tool for doing this. I have been thinking about using a flap wheel attached to a drill or would the good old ginder be better.

Cheers

PS I have done a search and found 1 post that mentions flap wheels but nothing recomending or condeming them

have you thought of using nitromorse (sp?) and a flat scraper? that would take the majority of it off and then use a wheel on a drill to take the rest of it off

get a wire brush attachment for your drill. I've found them a bit easier to use than a flap wheel, and much more precise that nitromors. If you get nitromors slightly wrong, you'll end up doing the whole panel!

Finish the area you've just removed by hand with some 800 grit sandpaper, then prep and paint.

A decent wire brush wheel or cup-brush on a grinder spins much faster than a drill and is seriously good for getting back to bare metal quickly. It is noisy and dusty and will also remove any unsound metal, trim, fingers etc.

The ones Frost sell are top quality.

Cheers for the advice

For info I found a couple of groovy griner pads at the Popham show. One was like a flap wheel but laid down and one was a tough nylon thing which seriously attacks rust and paint but is not strong enough to damage the metal - result. Had a go last night and went from
