i found this car polish in my garage thats 10 years old. Its the old school simoniz polish. Out of all the polishes ive ever used this is by far the best. also it brought all the aluminim parts in my engine compartment to a bright polished look. The parts were almost chrome. i was curious if anyone knows if the newer simoniz polish is the same mixture as the old. i just thought id post this in case anyone comes across this stuff. it also brought my paint job to brand new looking shine and got rid of all those swirl marks which my car has received over the years.
