Hi I had an additional problem with posting pics, my Mac labelled images as jpeg. Mayhem would not accept them, then another member explained that all I had to do was to edit the Suffix Jpeg by simply deleting the letter "e"
Now I simply rename pics, email to myself and save in a "boatpics online" file.
I have found a decent pinstripe product at a local model shop which is a roll of pin striping of varying width, it is a bit thicker than I would like but a good thing to have to help choose the right width for a task.
I used a local graphics firm to do a job on my car and have found him a very useful contact, one advantage of talking to a professional like him is that I have scrounged a few offcuts, the other is that he can source so many colours, a light ivory/beige for example might look more pleasing as a deck caulk than brilliant white.
There is another alternative where a contrasting stripe is required and the deck is plain dark wood, if the plain deck is in good condition one could order some clear vinyl wrap with the chosen pinstripe, at the chosen spacing, already applied. This way you get perfectly spaced stripes in extremely thin vinyl and a perfect, high-gloss finish that allows the existing wood grain to show through.
Modern vinyl wrapping materials have come a long way since Fablon, my graphics guy has recently started doing kitchens, with some pretty amazing results.
