I noticed some black spots on the boot and rear bumper. Looked like small spots of tar but where sort of hard and wouldn't come off with normal washing . I used a small dab of Prepsol (Wax remover) and they came right off:smile: . I have about 8 coats of Zaino (Z5 & Z2) over the past year. I doubt it did but, do you think the Prepsol removed the Zaino?

 

Yes, Prepsol will remove Zaino.

 

Not doubting your word Brad but, could you please explain why it would remove Zaino when Zaino is not a wax. (Looks like I'm going to have to re-Zaino the boot and rear bumper)

 

Whats zaino?

 

Think of it as a synthetic wax. It may be much better at withstanding heat and weather, but still, a grease-removing soap will remove it. If it removes tar, it's going to remove any wax polish around the area.

I usually use simplegreen on stubborn areas with tar etc, but only when I know I'll be putting another coat of zaino on the car afterwards.

Its very easy to test, clean an area with whatever soap you are questioning, and lightly spray it. You should see a clear difference in the water beading if the wax has been removed.

 

a grease-removing soap will remove it.I thought I saw a post here on nam that said Dawn would not remove Zaino Guess way too much info. for a bad memory

 

gooch...Zaino is a polymer sealant.

apexer...Zaino is only so strong. Prepsol will take it off. It's a pretty strong chemical.

A simple Dawn wash doesn't hurt Zaino like it does Carnaubas. But repeated Dawn washing will degrade it.

FYI: Sal Zaino suggests soaking tar spots in WD-40. This apparently has little effect on Zaino.

jwardell's test method is right on. That's what I do.

Dawn soap will absolutely remove Zaino from your car's surface, and you should do it about once a year then reapply your Zaino steps....make sure that you completely rinse down the car after soaping it with Dawn, as leaving traces of Dawn soap, then applying Zaino on top spells nightmares for your finish over time

 

I have to disagree from experience and discussions with Sal Zaino. Dawn is not a reliable way to remove Zaino (or any polymer) like you do a carnauba. The strong alkaline in Dawn might degrade Zaino but it won't adequately strip it. It would take a LOT of washing!

I was wondering why you remove Zaino annually. I have never found this to be necessary. What do you claim to gain by doing this? If you go a long time between coats (or if layering on many coats do this occassionally) simply wash with Z7 and reapply Z1 to assure a proper bond or you can use the ZFX accelerator which allows you to skip Z1.

I have a couple cars that have had Zaino on them for years with additional coats being layered on periodically.

 

Sal is actually the one that recommended to me to use Dawn to remove any build up of waxes in the paint before applying or reapplying Zaino.

 

I think the key word here is "waxes" Yes Dawn will remove waxes but, one washing with Dawn should have little effect on Zaino
