You're correct. While there is small selection of wine which requires a less than 100% airtight cork, most wines can simply be capped with ordinary bottle caps. While these cheap bottle caps outperform even costly corks (expect more than 0.50 EUR for a good quality cork!), they were, in the past, only found on cheap wines. So called "glass corks" are an alternative for the wine connoisseur. The manufacturer of these "glass corks" also offers "plastic corks" (identical, except made of plastic), but hasn't yet sold any of these cheaper variants. It's all just "perceived quality". Especially if you happen to know that the "glass corks" are only airtight because of a *plastic* seal. > I would think the first applications, if it is as good as they say, > are for building materials.

However, I'd be wary of anything which could emit particles. OTOH, plastic spray has been around for decades. After the solvent has evaporated, it's also chemically neutral. Yet I've still to see any "hygiene maniac" who covered everything with plastic.
