Just got my lock for One #3470 Mariana and decided against matte BSB since I live in central NH, where a Nor'easter is due tomorrow. Winter is always still here in March and basically is 5 months. So now I am thinking of how to best protect my Mariana metallic. In the past, I have applied DIY Zaino products to get that deep wet look, and have done up to 3-4 layers per season with fantastic results. But now I cannot put in such effort, and am wondering about 3rd party ceramic coating. Do I do PPF on front, and ceramic overall? Who does this in NH?
