Hi,   Having looked through the posts it would seem that the best thing to do with the joints between wings and body is to use a flexible sealer.   As the post I saw was a few years old please would somebody recommend which is the best product and where to get it. I have seen that silicon based products should not be used, is this correct.     The intention is to fit all the panels and then send away for spraying (trying to keep spray shop labour costs down), this brings the next question
