I could get really into it now and advise against the z8. it's great on it's own but it can work to compromise the work you,ve just put in with the z2. It won't add to the finish I promise, 2 coats of z2 with a quick detailer on to tidy up any bits will leave it as good as anything.
For anyone who wants to know why, z8 is primarily a spray and wipe sealant for untreated paint. In that application, it's absolutely brilliant. Now, I suspect there are some solvents in there which are there to ensure an even coverage. There's nothing wrong with having solvents in, there important in a spray sealant. But as you can imagine, these will have a detrimental effect on any underlying protection. Now, these might be small, but when you consider the work you've put in, in applying two coats, you won't want anything taking away from it.
In it's own field, as a spray sealant z8 is great, but over existing sealant, not so great. It's hardly going to dissolve your z2 in seconds, but it would be careless to say it won't have any effect.
Sorry if that's a ramble, I've typed it on my iPhone.
I've tried to present it in a way where each reader can decide for themselves how to take the advice, but it's all worth bearing in mine after sweating your nads off applying z2!
Happy detailing
Hi JPC,
Apologies and no disrepect meant, but I have to totally disagree with that statement.
I have used Z8 for well over a year now, and from my own personal experiance, and from reading about it on Detailing World from seeing how the 'pro's use it, I can say you are wrong in this instance.
My argument is substansiated by the following,
Taken from the Zaino website, link below
"Z-8 Grand Finaleā¢ Spray Seal:
Leaves a high gloss, high shine, deep, rich, wet finish thanks to advanced optical-clarifying polymers
Leaves an ultra-slick finish that repels dust, dirt, environmental fallout and other stains
Locks in the improved looks and protection for weeks - not days
Contains anti-UV agents to protect your vehicle's finish against damaging sun rays
Is easy to use: wipe on, wipe off
Is intended for special occasions and events only; it is not a Z-6 replacement
Should be used in conjunction with the Zaino Show Car Polish System, including Z-2 PRO, Z-3 or Z-5http://www.zainostore.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=Z-8&Category_Code=ZainoThere is also a very useful guide below (from DW) to Zaino as people often get the wrong info about how/when to use each product.
http://www.detailingworld.co.uk/forum/showthread.php?t=30674Can you let me know how you came to these conclusions, was it from advise or from personal experiance?
I'm not trying to start an arguement here, and wouldn't have replied unless I was totally convinced it makes a HUGE difference to the longevity and shine of a car with Z2 or Z5 or even the AIO product on.
