Mga sir at mam, tanong lang po sana ako, ano po ba ginagamit sa mga Paint protect programs like, ziebarts, big bert's or honda's hydrophilic yata yon?

Kase I've seen a lot of questions here regarding having your car treated with those and they were all answered like "don't waste your money on those, you can do those on your own, they are just waxes that costs less than a thousand pesos" so what are those waxes talaga? I see that they have to prep your paint first by claying or using cleaners, then sealants, then wax if I'm not mistaken. So ano po ba ginagamit nila talaga?

TIA po sa mga sasagot
