How does Klasse compare to Zaino in performance? I know that Zaino has stellar cust service and shipping as well.
Zaino is going to last alot longer than just Klasse AIO on its own. However. the Klasse twins together will give you similar results as Zaino depending on the climate you live in. Here in south Florida we have very harsh conditions and I have yet to find a product as durable as Zaino to keep up with our weather.
Zaino looks good on most colors but on lighter colors it tends to look a little "stale". The twins will give the car a "wetter" look. If I'm doing a white or yellow car for someone, I almost always fall back on the Klasse twins. Klasse AIO and SG will really make a light car "pop". My routine after prep work for light cars is Klasse twins with 2 coats of SG on day one. Wait a week and reapply another coat of SG. One more week and apply a coat of Four Star PUPP. Giving time for all the products to properly bond. The PUPP is what makes everything just come to life, and I have yet to find anything as slick as PUPP. Almost makes the car feel slimy.
If I'm using Zaino, I'll do my prep, then apply Klasse AIO as a base and then one layer of Z2 on day one. Then additional coats are so easy I'll simply apply a fresh layer of Z2 every week or other week. The two bond well together.
Hope that helps,
Mark
