Well in my case we were allocated a case of what the supplier referred to as "paintable silicone/sealant" a couple of years back to field test, and which did what he said it would, i.e. sealed like silicone and was over paintable. I can't for the life of me remember the product name (I wasn't using it directly, but it was being used around balconies that I had formed), only that it was US in origin and that the tubes were a different size to the norm. And my suggestion was tongue in cheek because I cannot find a product like this listed in the UK (but then you can't find quite a few if the things we use on the Internet in any case...). Had I found it, I'd have posted a link
You weren't one of the two to whom I referred. I just thought it odd that two different members posted the same link to the Henkel USA website.
I understand their confusion given Henkel USA decided to call the product "Paintable Silicone Supreme". The product description however uses the word hibrid [sic] rather than silicone.
I don't want DIYers to come across this site and leave thinking that silicone can be painted over.
It takes 5 minutes to apply silicone and 10(?) times longer to remove it.
