Undercoating & Corrosion ~ 62 Lancer GT

I've already done alot of work on the Lancer, the outside and inside & under the hood is just fine. However, the undercarriage, well that's a job in itself! Lots of corrosion and build up from the salt used during the wintertime & it's age. About 3/4 of the original undercoating from the factory is still under the car, but the corrosion sucks!

Any suggestions on the best way to get all that off (with a little elbow gease, of course)...would like to find out a safe way with out damaging anything and what is a really good product to use for a new undercoating. I heard Spectrum is good...what 's your advise and tips?

See pics attached...YUCK! ~ Many Thanks, Bea
