A week ago, while tired at the end of 3 hour ride, I stopped on sloping ground and then tried to move off in 3rd = Stall and drop :-(

At least I managed to let it down gentle so fairing was not cracked/broken and only have deep scratches on lower fairing edge and mirror housing end from lifting it solo. I still do not know how I managed it but desperation helped as I was alone.

I have taken mirror to auto motive paint supplier and they have matched the colour in a spray can.

As I have never tried to paint the K before I need detailed guidance so I can learn as to the best method of application of Filler, Paint and Laquer (Undercoat?).

Currently I thought -
Sand with fine? paper
Filler (Isopon)
Sand (mini orbital with fine grit) to shape
Wipe with de-greaser wipe and wipe off
Undercoat?
Paint (How may layers? and sand between layers?
Laquer (How may layers)
Polish
Admire result?

You all seem to have this knowledge from your restoration projects so I thought I would seek practical guidance from the experienced to bring it back to an object of beauty again and maybe some good has come if I can master painting.  :-)

If you polish the bike and most of us do then some solvent like prepsol is needed to remove any wax or silicon first then sand with 400 grit till there is no shine on any part fill the scratch with spot putty or primer/filler (which is what I use) then fine sand 600 grit till no holes hollows or wrinkles then a final undercoat very light and wet so that it almost shines then dry rub with 600 grit, wipe over with prepsol and dry well then start applying the top coat. Dont get too enthuastic with paint but try to get a gun finish shine (paint is fairly shiny when dry straight from the can). With the paint that has pearlescent and fine metalic you may need to give it extra coats to match the colour, mainly for depth which will show as a slight colour difference in different light conditions.
If you make a mistake then don't try to fix it while wet, let it dry and sand out the sags/runs (we don't want your mates calling you "niagara" do we) and put another coat on.
You may be able to fix just the scratches on the fairing by just spoting it and wetting the paint into the present coat but with a rattle can I think that would be a difficult job for even an experienced painter.

Check your local directories for mobile paint repairs. They seem to be quite common now.

I made the same recommendation to a neighbour who scuffed his car door mirror badly. The bloke who came in a van analysed the paint, mixed up a match in his van and did the repair for twenty quid.

You wouldn't believe it had ever been damaged.

I decided to do it myself as part of the fun of running an older bike is adding to my skills.

From my auto paint supplier I got tube of filler, papers 380/600/2000 grits/, de-greasing wipes, paint, clear coat.

I did the filling, sanding, de-greasing, painting, clear coat but was disappointed with result so went back to the supplier for advice.

He recommended re-coating mirror by rubbing down with 2000 grit and re-applying clear coat but raising it from the flat surface I had put it on as the side did not get properly coated the first time. Then rub down with 2000 grit wetted with water with a bit of detergent in it. Then polish with the auto painter's polishing compound (another purchase) before waxing polish.

Did all that - it looks OK for my first attempt :-)

But I know where I can do better next time. So skills partially acquired.

Yeah thats a pass. Its a bit like welding,I have been doing it for 40years and I have people say that they cant even use a little home welder and my reply, nobody can use a little home welder you need a good welder and same goes for paint. To get the best results you first of all need the best equipment.
So with a rattle can you have done well.

Dotheton has a really good reference thread on rattle can paint application.

Rattle Can Bling

Another good online resource for painting and paint correction is the Autopia forums where you can read up on paint correction techniques. There are many how-to articles that detail the steps to be taken to correct flaws.

The above website gives a great account of why you are going to do heaps of faint coats to get that perfact shine. my experience lead me to ensure I seal coated it before i used undercoat or putty. My paint seemed to lift in short sections so ended up sealing it then doing the paint prep, hope it helps

Nice job Notts anything higher than that would require one of those high speed polishers that can burn the polish and paint if not handled with respect you are at the top end of private painters I'd say.

Thanks to all for your comments and advice.

Also it helps to have this forum and a friendly auto paint supplier that does not object to novice questions.

My friends have seen what I can do.  I have been asked to touch up my brother's MX5 and a friend's Corsa. Is this a new line of work?

Probably not.  My skills are not that good but I do have time and patience on my side to attempt these small items.
