Does couvre work well with toppik - newbie

[Blakeynz]

Have ordered both and wondered if couvre works well in conjunction with toppik as I heard couvre doesn't come out when swimming.

How is it applied, is it easy to use or a pain?

Any other concealer products that work well with toppik? Toppik is great but feels a little synthetic.

Any info is appreciated.

Cheers
