Re: Meguires All the Way
My favorite Meguiar's product - Hyper Dressing.
That stuff is amazing for engine detailing, interior dressing, and also for your vinyl / rubber trim and tires. It is water based so it won't last thru multiple washings, but it rinses clean and won't build up. Put about 10+ coats of it on your dash and you'll be impressed.
Just after the first application you will immediately see how your dash soaks it up so be sure you apply the first couple of applications evenly.
