Does anyone have any experience with the Meguiar's M21 Synthetic Sealant or synthetic sealants in general. I'm thinking about trying this product out this spring and would appreciate any advice. Thanks.

Thanks for the info. Is the sealant something I apply over wax, under wax, or in lieu of wax? I was thinking the wax may prevent the sealant from adhering to the fiberglass. So it may need to be applied first.The Meg 21 is a good sealant, long lasting, and fairly easy to use. I have used it on cars and it does well. It becomes somewhat subjective on a comparison to other sealants, but generally is is as goos as others from mothers, griots, chemical guys, duragloss, etc.
I have not used it on a boat, but I would expect it to perform similarly. Not sure I would select it over other choices, but no issues.
