Mask with strips of around 12 inches overlapping each piece and inside of rim, rub down and around edge of tyre and rim to get a good bond

when you have a good firm bond use small slightly rounded piece of metal (I used 8 oz Hammer) to rub around edge of rim until rim shows

Remove unwanted tape from inside the rim area

Use blunt rounded flat knife (I used a putty knife) and run it around edge of rim next to tyre and finish off
running your finger around to make a good bond with the tyre

As you can see in the last picture a nice tidy finished edge after painting, I know this will wear with use
when driving but looks tidy to start with.

Hope this will help anyone wanting to paint their wheels
