So i went on Adam's Polishes store page and got the Iron Remover and the Pumpkin Spice Detail Spray plus the mega foam and a foam cannon. My question is I have never really been the type to wash my truck I usually pay someone to do it but i want to try it myself. Out of everything I bought from their store what would I use first the Iron remover or the pumpkin spice detail spray? cause of course the mega foam come first also i got the 2 buckets for the "double bucket method" can someone give me their I guess system of washing a truck??
