For a long time now, I've always had to polish and wax my truck every 2 months (3 months at best). This is using a pricier, quality wax such as Meguiar's Tech 2.0. If I use carnauba-based wax, you're looking at a week at best. Climate conditions here are rather extreme - intense heat, dust storms and when it rains, it rains mud. You get swirls without having to resort to improper washing techniques. I last detailed my truck in January, and have since been using Meguiar's Mist & Wipe twice a week (I wash it daily). The paintwork still has that wet look, swirls are very minor (you have to look hard to see them under good lighting conditions) and the paintwork isn't dry as it would have been. Costs me about $8.25 per bottle every 2 weeks, but it does a good job. I was wondering if anybody had any other suggestions, which would do an even better job? Are wash and wax products just as good? Sonax of Germany has a good wash and wax shampoo I was looking at. Thank you!
