Meguiar's ultimate compound.

Tried on my mom's myvi which got rust mark and water spot on the windshield. Clears everything. Applied with polisher, using manual by hand is too labor intensive. It is supposed to be really mild abrasive, so it should be safe.

This evening tried it again on my windshield to remove some weird oily spot. After the application, it seems that the compound has revealed numerous small chips on the windshield. It's a 13 years old car, so maybe it's normal and wasn't caused by the compound.
