I had a small ding when I reversed into a letter box post. It was very small but just large enough that try as I might I could not ignore it.
The paint code can be found low down on the driver's side B pillar, in my case that was PNT Code
BCW.
For $81 I purchased three large (created on the spot) aerosol cans; base colour Catalina White (Paint Code: PBCW known as Solid White in Tesla speak), top clear coat and some primer filler that I did not use) some wet and dry abrasive sheets and a pot of filler.
That all came from: Harts Industrial Paint Supplies of 425 Newman Rd, Geebung Qld 4034.
Note: Colour match was perfect and they did a good and easy job but they are not the same paint type as used by Tesla.
I also spent $500 on the correct paint which comes as a two part base colour with separate hardener (I bought 2 litres) plus reducer, one part clear coat (again 2 litres) and reducer and another can of filler.
The reducer thins the paint to a viscosity suitable for spray painting.
That correct paint came from: BASF Automotive Finishes and is known as Glasurit waterborne paint.
I got mine from: Prestige Paint and Equipment Supplies, 1/11 Woomera Place, Archerfield, Qld 4108.
I have not used the Glasurit stuff yet, I understand it has a guaranteed shelf life of 6 months. I recently purchased a couple of cheap spray guns to use with that paint. Maybe I'll paint the wheels with it.
I have zero skill in this area but if you take your time and don't rush it's easy enough to get an apparently perfect result.
Any other colour than Solid White or Solid Black might be a much bigger challenge though.
If a small amount of panel beating is required here is a link to a video I found handy:
