If you find the autoglym bumper gel tends to make a waxy mess in the rain, I heartily recommend Chemical Guys Fade to Black (it's an aerosol). Be sure to wipe it down completely with a microfibre towel once it's dwelled for 30 minutes or so.
Nowadays I only use bumper gel if I need to get some polishing residue out of non-black plastics. It used to be my go-to product though
