Concrete staining is one of those things that seems minor until you try to sell or rent the garage space and suddenly those permanent marks become everyone’s problem. A UK made drip tray is genuinely worth the slightly higher upfront cost for exactly the reasons you already identified which is material quality and heat resistance. I have had one under a project car in my Ajman garage for nearly two years now and it has not shown any cracking, warping or brittleness despite sitting in a garage that regularly hits brutal temperatures through summer. Crateco supplies the UK made ones and they are based in Ajman Industrial Area which honestly surprised me because I assumed I would need to source something like that from Dubai. They have different capacities so if your Jeep is a heavy leaker during active repair phases you can go for a larger volume tray rather than having to empty it constantly during a long work session.
