Steve at Dentz in Worthing or Lee in Eastbourne

We (as a club) have used them several times.
I failed to use them on the K1 the other week, instead I went for the guy my local SEAT dealer uses. He did an OK job but his attention to detail and the final finish wasn't quite as good as I'm used too.
I will use Lee/Steve next time, as my experience with them is they keep working the dent to perfection far beyond what I can see (and you know my attention to detail)
