Co-worker had a '62 Impala bubble-top, white, VERY original car. Shortly after buying it, he decided to use a product (don't remember exactly what the brand was) that was essentially a wax with a small bit of compound in it that was supposed to take down a small amount of oxidation and bring back some shine. He starts on one side following the instructions on the bottle, when he gets down applying the stuff he looks back to where he started and sees the paint bubbling.hoses/wipes it off, tries to call the manufacturer and they blow him off, saying it says to test on a small panel before use. Calls Hagerty and tells them the story, they say email pictures. They had him a check within a week to paint the ENTIRE car.

I've used them for for 20+ years with never a claim. Checked prices occasionally and they've been cheapest for me, but as was said everybody is different and so are their insurance rates...
