well this afternoon i have fitted a new off side rear lamp cluster, the old one was cracked.
£45 from ebay.
then i set about polishing the headlamp covers - being plastic they begin to fade over time with UV damage. a gentle scrub with a damp sponge scourer, and a thumbnail of toothpaste (yup), works a treat.
toothpaste also good for other hard plastics, rear windows, lamps, etc. minty fresh!
best thing for external textured black trim?
peanut butter (smooth) - the natural oils work a treat. just rinse off well to avoid being chased by wasps
