Require cleaning weekly. Up until December 2003 we would have been embarrased to sell the only chrome boot hinges then available. They were very bad fitting, looked poor quality and had so much play in them they were totally useless. But along came a set which do fit and is of fairly decent qaulity for the price, if looked after, but beware because of their position on the car they are difficult to keep bright, unless great care is taken of them.
As everybody is aware, everything in the British climate oxidises and rusts.
Painted hinges are probably better proposition in this instance unless you really must have chrome. The only upside is, at this price you can change them every few years. Comes with fixings but no gaskets.
