OptiSeal instead of Collinite 846?

[new2mud]

I`m still getting a handle on the myriad of products and their uses.



I understand 845 has incredible longevity of effectiveness.

Would OptiSeal be used instead of 845, or used on top of? Under? *confused*



eta: correction of Collinite 845, since 846 was made up in my mind :D

I would use it on top of it.

On top is probably the better choice. And BTW, it`s Collinite 845 :)

Haha--see, all the numbers and letters to learn are getting to my cluttered mind!
