Worst: I bought some low gloss tire and rubber stuff while I was waiting for the Sonus and Griots. That stuff smelled so bad I got a migraine. I do not know what brand it was because I threw it out!
Worst is any APC, they all have the stale Citrus/Chemical smell to it. Another awful product in the smells dept is Iron X spray and Iron X Paste...god awful smell. HD Poxy has an awful smell to it also.
Best? Most of the stuff have a fragrance to it. I like ONR and Dodo Juice Born Slippy.
I have a strange one. I like the smell of DP Interior Surface Protectant but after applying it and it sits in the sun, there is a very bad chemical smell that develops that gives me a major headache.
Anyone else notice this? I love how the product looks but I can't take that smell afterwards.
