How to deal with lugnuts that have been exposed to corrosion

Corrosion Block can save you major headaches when it comes to
changing your tire on the side of the road. Ever get the tire iron out,
roll out the spare, and find that you can't get those lugnuts off?

It's ok. We won't make fun of you this time.

Corrosion Block makes it easy to work on seized lugnuts

Already stuck? Blast some Corrosion Block on the lugnuts and let it sit
for a few minutes. It will penetrate into the corrosion and help to free the
seized lugnut. Now, before you put those lugnuts back on, liberally
apply Corrosion Block to the threads of the bolts.

Not only is it easier to work on your tire now, but it's also healthier.
You will be less likely to round off edges of the nuts or strip threads.

Next time around, they will come right off, and you'll look a little tougher.

Corrosion Block is a clean, clear, ultra-thin fluid which leaves a non-greasy astmospheric barrier to protect the base metal on interior surfaces. It leaves no gummy residue, and it can be sprayed on, or wiped on with a damp rag.
