Id go with Klasse AIO and Sealant for the Silver Tacoma,I have a 2004 Lunar Mist Silver Tacoma TRD and use Klasse AIO and ,Detailers Pride Spray Sealant on top. One thing Ive noticed with Silver is it doesnt have any pop to the color so I feel using a carnuba wax over sealant isnt going to help set off my trucks color in any great way,so I reapply sealant coats it gives a nice shiny clean look but no depth,youve probably already noticed this with your truck,I'd definetly go Klasse Twins

for ease,durability and cost $$ on both trucks.
