Undercoating & Corrosion ~ 62 Lancer GT

Kleen Strip Aircraft paint stripper works well on the undercoating. Most auto supply houses stock it. Wear a face shield, gloves and long sleeves, you don't want this stuff to touch your skin, it burns like the dickens. Let it sit for 15 min. or so and scrape it off with a putty knife. Any residual can be removed with coarse steel wool. The crusty rusty will be a nasty job. Wire wheel on an angle grinder is how I usually get stuck doing it since I don't have blasting equipment. Have fun!!8)
