wfedwar said:I feel your pain. I have a 4Runner with permanent etching on the hood that appeared after only a couple of months while wearing Zaino. I had similar etching on my truck, but caught it before it became permanent. Pollen+light rain+Zaino seemed to cause the problem very quickly. I've talked to swimming pool owners in my area and they tell me it is almost impossible to keep the pH up when pollen is bad. This is probably specific to the plants in your area, but for me it means pollen is acidic. Couple that with a strong-beading sealant that offers little protection and you get problems. That last sentence is my read on the issue. I've tried a lot of sealants and waxes and the most protective I've found are the acrylic sealants (Klasse, Werkstat). This makes sense, as they are weaker beading and the polymer is acidic itself, and therefore not as vulnerable to attack by another acid. There is/was a thread on the OCC board where Dr. G described this very same thing, and as I remember he listed protection from acid rain spots as one dimension where acrylic polymer sealants outperformed other sealants.
I know that Werkstat is acrylic based. Is Optimum? I didn't think they were? :think:
