the majority of my frame i stripped with a 4 1/2 angle grinder equipped with a large wire wheel. just be sure to use some type of sealer if you go to smooth bare metal, otherwise the rust will come through once its subject to moisture ( parked in the grass for a week or less). POR 15 likes to have "tooth" to grab onto, so if its not a show truck just hit it with the wheel, use some wax and grease remover or laquer thinner to clean the metal off and then put on a few coats of the "black magic" and then spray some underbody coating on the "high traffic" areas (rear wheel wells, front spring buckets, and anywhere else that gets blasted with the elements).
