Solid white mah! sure no CC loh!Orange peel cannot really say much but for Perodua, their white cars initial few batches didn't use lacquer. Just base coat white and settle.
Then all their apple green cars all faded to almost goldish colours. Polish also cannot get back the green. No UV protection?
Your wife's Mivi, and I have a friend also Myvi, lime green, now yellowish.......hhahahhahaha
