Good afternoon,
I know its been over 10 years on this post. I had a quick question if you have time. On the oven cleaner to remove undercoating. I am in the North East and my car is no longer a rolling chassis to roll outside. If I apply the oven cleaner, do you think I could scrape off the undercoating or do you feel any cleaner that does not come off right away with a pressure washer may damage or rust bare metal parts?
