Dying Interior panels

[rod1701]

My 70 Suburban project has white door and trim panels. They are in pretty good shape without tears but they are stained from 40 years of working, hauling, sunlight, and likely sitting in someones back yard for quite a while. I am trying to keep this on a super low budget so I would like to salvage what I have.

I have tried interior dyes in the past on an El Camino project that I had about 15 years ago. It didn't turn out that great. I'm sure that paint/dye tech has changed for the better. Does anyone have and suggestions, tips, tricks? I dont want to ruin what I have and I want it to turn out better than the last time I tried it.
