Automotive protective coatings have come a long way since your father’s can of Simoniz. (Which for the record is actually a different word than “Simonize” which is a recognized synonym for the transitive verb “to polish.” Who knew….)
There is an amazing variety of coating and sealants available today with prices ranging from tens to thousands of dollars. A professionally applied ceramic coating is a thing of wonder. But what about the DIYer? I’m going to stay away from the DIY ceramic coating for the moment (too many horror stories about water spots), and take a look at a couple of popular polymer coatings which promise 3-6 months of protection, starting with P&S Bead Maker.
