I have a leak in the aft port cabin and believe it is from the portlight. Before I rebed the portlight, I am interested in knowing if anyone has rebedded theirs and if they have any advice. Where might I purchase new trim rings if they break?I have researched and found that Sikaflex 295UV is for bedding portlights, any other suggestions? Has anyone replaced these ports through New Found Metals? I would appreciate any advice anyone can offer. ThanksCapn Bob
