Hi,
I too can heartily recommend Mr Jon Goodman's light seal kits. They are very easy to use. The pre-cut strips for putting in the main channels that the door engages with make it so much easier - you don't have to try and cut a 100mm strip 1mm wide!. The hinge end and latch end on cameras are easy to cut for any camera. I've resealed 5 or 6 cameras including SLRs, which are a touch more complicated. Olympus XAs, XA2s and XA3s are all dead easy. All you need is a good light, a sharp knife, some lighter fuel, an old cotton hankie, a bit of patience and 3/4 of an hour to do produce a first rate job.
The delivery charge, even to the UK was very small and to top it all he will even respond to e-mails and give you advice should you need it. This is not likely as his XA instructions tell tou all that you need to know. To top it all he is a proper gentleman of the old school.
