Glaco question re application?

[Daveb257]

Ordered some based on reviews and lots of positives on here but have what might be an obvious question?

Application of the compound, the online how to videos have it applied to wet glass, written instructions say must be dry

What’s the best choice?

That would help wouldn’t it ?
Glaco Glass Compound Roll On + Ultra Glaco

Brilliant thank you, always best to have a real world opinion
