For painting you need to order primer paint, base coat paint and a clear topcoat. You need to find out what paint colour you B is so when you call your local paint suppliers, you can give them the year that the car was made as well as the colour code.
You can get them to put the paint into spray tins if you don’t have a compressor and spray gun. If you spray with a gun, you will need to order some base paint thinners.
Please see the link to my paint supplier.

If you have tins you will still get a good finish if you take your time and follow a few simple steps.
1. Rub down the plastic panel with 800 - 1500 wet and dry paper.
2. Use a tak cloth to clean down the part.
3. Put the tin of primer in warm water for a few mins
4. Spray the primer 3 coats 15min apart
5. 5 hours later gently rub down the panel with 1500 wet and dry.
6. Use a tak cloth to clean down the part.
7. Put the tin of base coat in warm water for a few mins
8. Spray the base coat. 3-4 coats 15min apart.
9. 24h later if the paint is smooth and flat move on. If not gently rub down the panel with 1500 wet and dry making sure you don’t burn through the paint.
10. Use a tak cloth to clean down the part.
11. Spray the clear coat 3-4 coats 15min apart.
12. 24h later cut the topcoat with cutting compound
