WHAT TO USE ON EXTERIOR TRIM
 

hi all, can someone please point me in the right direction for an exterior trim cleaner/protector. ive tried armoral, autosmart finish but results are always streaky and dont last long, esp if raining. what do you all use?
best regards, robbie

303 aerospace protectant. nuff said ;)

If rain proofing is important to you, then Meguiars Al Season Dressing is good and worth considering too. It is solvent-based, whihc helps to give it greater purchase, and hence durability. Our favourite product for exterior trim use (if we feel the need to dress them - in general if trims look nice we don't dress them). :)

excellent, will try that then, just hate the streaked stained look of them. living in the borders it always rains so if it could withstand the odd shower all the better. thanks for replies

I find 303 rubish for external trims you get white lines when it rains

Megs ASD again you get runs but not as bad as 303 I still havent found a product that actually works

both products applyed to a clean surface neat and both buffed off afterwards, also tryed not buffing but still it streeks when it rains and looks a mess :(

Hmm i agree....i coated the black part of my front grill with aerospace and left it to dry naturally, came back to find the grill is all white streaks and white marks which i cannot shift with nothing, any ideas why this hashappened?

However, used it on my engine bay and it came up very well and still looks good 2 months later, just pi$$ed off about my grill:mad:

Strange, never seen streaking with ASD, yet we apply in the exactly the way as you outline? Confused! :confused:

Hmm, have you tried P21S Total Auto Wash, agitating the affected area with a soft brush? I'd be surprised if any underlying staining has occurred; 303 is water-based after all. As you confirm, 303 is superb on engine bays, but no good for exterior use. :)
