Been a busy lad and replaced the dark and tatty alloy wheel centre badges.
Bought these from ebay and coated them with lacquer before fitting. To remove the old badges I drilled a hole through the badge and cap. Then used a small screwdriver to prise the badges off via the hole drilled. Cleaned the surface and applied the new badges. Doesnt look bad at all and cost only £10 and gives the alloys a lift in appearance.
