Is the haze on the bonnet actual oxidation or just fine swirls? That changes whether polish is enough. Also, do you park in the open or under cover at work? I’d like to hear what your colleagues who tried film actually paid.

Fixed mine early after noticing the idle shake and it was a relatively simple and affordable repair, glad I didn't wait since letting the engine move around more than it should during acceleration apparently puts extra strain on other parts over time.

Getting back on the road before needing roadside assistance is the right priority here. A genuine Amaron 55B24LS from a certified dealer with a fresh date and proper warranty is a same day fix for a Sunny without any complications.

Similar story for us, started with whatever was available locally when we were in a rush to set up, ended up replacing half the batch within a year due to cracking. Going direct to a manufacturer for consistent industrial grade crates was one of the better operational decisions we made, wish we'd done it from the start instead of trying to save money upfront.
