Under Coating Removal

I thought I let you guys know of a product that cuts Under Coating fast and does not hurt the paint. It is made by Finishmaster, It is there #300 bug and tar remover. The original owner of my Cuda had rustproofing sprayed all over everything inside of the engine compartment and it looked like sh!t. So I talked to a guy at Finishmaster and he sold me a gallon of the 300 and it only took 5 hours to make the engine compartment look like new. I sprayed it on with a spray bottle, let it soak for a short time then used a plastic scraper to take it off.
