My Sedona has developed a slow P/S leak since I bought it last August. The main rack looks damp, but that's all I can tell. Maybe the extreme cold has something to do with it, I do not know. But I'm looking for a decent stop-leak P/S fluid. Anybody tried some before? Yes, I know that the only way to stop leaks for good is to fix the issue, but I really do not have time for that right now. Plus, it's way to cold.
