Black looks really good. I bought 4 cans of Rubberspray and decided to paint my tires black. Bear in mind that this does not protect the rim and it can get scratched off so be careful and do not use a high pressure washer on the tires.
The application part is really easy and anyone can do it. I know nothing and managed to get a decent result.
Here are my pro tips:
REMEMBER TO WEAR A MASK
Clean your tires
Use the whole Can at once, do not stop spraying until the can is empty. First layer will look something like this. Just spray and keep the wheels close so you can leap to each tire.
2. Keep your cans warm and stop if there is little gas left or else you can get drops.
Don’t worry about the drops, you don’t see them later.
3. Minimum 4 layers. 4-6 is recommended.
End result is cool.
Wash with care!
