I've read several posts on the topic of countersinking (or dimpling) the tank skins at the baffle. The debate has to do with being able to seal it properly if you've got all those pesky dimples where the baffle needs to slide in. Based on my own experience and what I've read, I'd much rather dimple than countersink these holes. And I've read that dimpling has been done successfully. What I'd like to know, however, is if anyone has dimpled these holes on their RV10 tanks and then succesfully got them sealed?
