Hi Folks, I've been looking at those scratch repair pens generally available. Although relatively inexpensive I'm not yet convinced they work all that well and would appreciate any advice from users? I suspect they're only any good on relatively minor surface scratches and don't want to fork out unnecessarily. Thanks.

Bloke next door sells them on the net, he gave me one as a freeby and it's a complete fail

No good whats so ever and quite expensive

How can a pen full of a clear Lacquer like liquid repair a scratch?

Thanks Auric Goldfinger. After further review I've decided not to go down this route. The claims are well overstated by those selling!
