You asked the magic question that your thread was trying to uncover. I had mentioned that my father’s car came back to me at 6 months and still had beading, not great but appeared to still be protected.
There’s numerous ways to kill an aged sealant. If you have any IPA or paint stripper, that should do the trick along with claying. Or alone should remove it. There’s also alkaline prep soaps, paint cleaners, etc., but I assume you don’t have these. A polish itself could be used as a paint cleaner simply by quickly spreading over the car with minimal working it in.
I’m telling you way too much for the sake of info. Just clay thoroughly and if you don’t have IPA maybe you want to consider it as it will make the surface free of oils and stuff that will impact your Hydro Blue or other SiO2 products you want to use after. Or get Klean Strip Prep-All as an IPA substitute. Others here can let you know a good IPA ratio if you go that route.
Thanks I appreciate it. Great post.

I did read, on here I believe, that IPA doesn't work that well stripping sealants. Thoughts on that? If so, I can try the other things you mentioned.
