I have used Optimum spray wax in the past and got away from it because it tended to streak. After several trials I settled on Souveran spray wax because I liked the look and the ease of application...however...durability was not its strong suit. Recently I got a sample bottle of the new formula that supposedly has been improved to last longer. I got a pretty weekend, stripped the truck with CG wash and gloss used at the concentrated level to strip. Clayed, did an alcohol rub down, followed by a coat of CG Blacklight. After the Blacklight I put two coats of the new Souveran spray wax with about two hours between coats. The truck looked good and I thought I had a combination that would look good and be somewhat durable. The truck sat outside through one rain storm with the weather never getting over 70. When It rained the water would bead like crazy! We finally had a decent day and I decided to wash using CG Citrus Wash and Clear at less than the recommended amount for a maintenance wash. To say I was disappointed in the results is an understatement. After the final flood rinse there was no more beading and the paint was not slick! Am I expecting to much from a spray wax ? Need some advise because I don't understand such a poor performance from the new Souveran formula. I am now debating on going back to OCW but don't really want to deal with its quarks. I am looking for a spray wax that will produce a good shine, is easy to use with out streaks and some durability. Quite frankly Meguires Quick spray wax fits the bill but lacks durability. Whats out there that will fit my demands?
