I restored the plastic lenses on my Mazda using 3M Imperial Wetordry sand paper, with 400-, 600-, 1000-, 1500-, 2000-grit and then following up with Meguiar's #17 (plastic cleaner) and #10 (plastic polish). Looks great but requires a lot of elbow grease. Finer grit sand paper would have saved me mucho time for sure. mpower1226, do you remember the name of the store at Pacific Mall?
