I asked the same question:
Gentlemen,
Have a new car, Acura MDX, Nimbus Grey Metallic. Purchased Prime Acrylic, Acrylic Jet: Trigger and Acrylic Glos. I hope to detail my new car in a week or so and have a few questions:
1) How long should Prime Acrylic dry (cure) before putting on Acrylic Jet: Trigger? On the web site it says to wait 30 minutes before buffing off. Is it OK to add Trigger then or would it be best to wait a while?
2) Is there any benefit to adding a second coat of prime prior to applying Acrylic Jet: trigger?
3) After applying Trigger, how long should I wait to add a second coat of Trigger?
Thanks!
Here is the reply:
Thank you for contacting the Werkstatt with your product questions. Congratulations on the new Acura.
1. The standard 30 minute wait time is perfectly sufficient before applying Trigger over Prime Acrylic. The vast majority of the curing of the polymers in Prime occurs within this time frame. You can add Trigger right after buffing or wait... there will be no real difference in the result. As a tip, if you apply Prime Acrylic in the optimal very thin coating, such that there is fairly little residue, you can save a step by just applying Trigger without first buffing the Prime. The action of Trigger application will clean off any of the Prime residue.
2. The primary benefit of a 2nd coat of Prime is just to ensure complete coverage, with no missed spots. It is not able to layer itself due to the cleaning and polishing action. There may be some benefit of a 2nd coat particularly in areas where the paint may be more contaminated, like around wheel wheels or side skirts.... simply to ensure everything is perfectly clean.
3. Like Prime, the polymers in Trigger cure quite rapidly. For best results, we recommend about a half hour to one hour between coats, if possible. That said, it is possible to layer even sooner; Trigger is a very gentle formula and doesn't readily disturb base layers, even ones that haven't completely cured. For best results, the whole system should be allowed to cure for a full 24 hours before exposure to things like detergents... this allows for the last, small percentage of polymers to crosslink.
Hopefully this has answered your questions. If you have any others or need clarificatioon, please do not hesitate to email again or reply to this message.
Happy Detailing!
