You guys are wimps.... I like the smell of 90W.

sulphur

I don't have a garage, but since my place and others is above where we park, I'd say it's when a sewer line backs up and leaks from the access holes.

My employee:eek:

Engine degreaser is pretty long lasting as is the smell created by using an abrasive metal cutting chop saw. Neither of these smells is putrid per se, but they impermeate ones clothes and last for days.

When I was in a service truck I used this stuff called "Rust Buster".
I have no Idea what was in that little bottle, but it would give you a nasty headache from the smell.
If I needed it I would buy it and leave it on site so it didn't have to be in my truck!

gear oil. I don't think any automotive smell is worse. (assuming nothing is on fire)

Yep, Sweepco transmission oil. It seems to soak into your skin and last for a while.

used swepco. or any gear oil.

having said this.my front diff is leaking at the drain plug on my tacoma. i have a half used bottle of swepco, i am going to put in. gag.

Old nasty gas is the worst, kroil is the best :)

Purple Power degreaser mixed with some combination of carb cleaner, brake cleaner and/or Simple Green. Whatever it was, it really stunk.

The smell of failure used to bother me, but I'm used to it now.

Yeah, but we have the common decency to keep em in the freezer where they belong.

helps if you cover it up with the sweet smell of "HOPE". it's like febreeze for failure. hahah., cussing helps too.

I use that at work. Smells great! Similar to Seafoam Deep Creep

Someone already did Sid.

Worst is this fire ant poison I have from when I lived in Texas, no fire ants here, so far.

Old, used 7808. Smells like sewage.

Thanks for the belly laugh.

the jug-o-pee

I'll second this one for my shop!!!
