Paint he powder coating on the left hand side of my monster is coming off. I can't see that I could dismantle enought to take off and get re-coated. Anyone got any handy repair tips - someone suggested hammerite - anyone got any experience of this????

This looks like you have a coffee table that has been powder coated (I may be wrong). This process allows for a very nice looking finish, but if it is chipped, it can't be fully repaired in the same way you would repair a regular painted surface.

To legitimately repair it, the entire table would need to be sand-blasted down to the surface and powder coated again.

As I'm sure that's not the solution you'll want to do, I would simply suggest a patch-job. Find a paint marker (similar to a sharpie, but instead of ink, it dispenses paint) which closely matches the paint of the table. You may want to pick up several shades at a hobby store of sorts. Simply apply the paint on the area so it doesn't draw the eye's attention. You'll know it's there and be able to see it, but in most cases, no one else will.

Try not to get any paint outside the lines of the chip. Keep it very localized.

You may want to put several coats on it to build it up.

If the table is wood and not powder coated, go to the store and get some putty to fill the hole and some fine-grit sandpaper to smooth the surface once it has dried. Once you've done that, you may paint the area according to your taste.

when you paint wood all you do is prep it then paint it u dont have to bake it ive never heard of anyone baking wood after its painted

The paint shops are likely correct, but there will be a number of powder coating shops that may be able to match the color. The powder coaters, coat many things like pool fencing.
You may have some success if you sand back the cover ,apply a aluminimum etch primer and then an epoxy paint.
The powder coating will probably last longer, as the alloy will eventually corrode under the paint and start to bubble.
If its a show quality bike, you may need to dig deep and get a new one from the trumpy dealer

there is no going back, you have chemically changed the powder coat composition. Learn your lesson well and next time use a H-D listed cleaner and a very soft brush.
