Hi all Discovered a fuel leak coming from what appear to be two screws on a lower panel. Read DMax article and what was available her and have a couple of questions. By DMax article, seems like nut plate cracks are the typical culprit in this circumstance. He says remove a screw, apply sealant to the thread and replace. Wow sounds easy. But this is a Mooney fuel tank system after all. 1) Screws are seized. I don't want to damage them and am afraid of creating new leaks on this panel if I take an impact to them. 2) the panel location is just below the filler cap, so I can get a great visual on the sealant there. Looks like a minuscule crack in the sealant along the nut plate IA is on vacation, so we'll be talking when he returns. What is the group consensus - remove panel and reseal or patch seal from inside? Seems like option 2 would be the good is better than perfect option but I'm hesitant to add layer upon layer of Proseal. Thanks as always Brad

A previous owner of my M20E used some nasty black sealant (RTV silicone?) for the 2 access panels at the base of the windshield. This stuff got onto the cabin cover, and then back onto the panels & cowling. I'm going to be replacing the cabin cover and I want to reseal the panels with something that isn't going to make another mess. What is the spec requirement for sealing these panels, and which sealant has worked well for you? Is there anyway to check that you've sealed the panels adaquately, other that putting enough on to see it ooze out everywhere? Any suggestions on what to use to completely remove the black marks on the white paint? I don't think it's going to come off with any ordinary cleaners or soaps. Thanks! Michael
