Digital BW, The Print

I have searched the archives and come up with a variety of 
information but would like to post a question about varnishing. I 
have been playing around with Golden polymer gloss varnish and 
really like the finish after about four coats. This has been 
successful with prints I've had around for awhile.
However, newly printed prints are smearing. I have tried some 
sennelier lator fixative but it doesn't seem to help (or I am not 
waiting long enough). Some questions:

1)I found Lascaux is very popular. If I am going to use a gloss 
varnish over it do I need Lascaux or will something else be fine?

2)How long should the print dry before adding a fixative? I use UT7 
on photorag and photorag satin.

3)After the adding the fixative how long before varnishing?

Basically, all I want if for the ink not to smear when I varnish 
with a water based varnish. So how is this achieved. I assumed that 
all I needed to do was spray it with some fixative and then it 
wouldn't smear. I am having mixed results. I am testing a variety of 
things, and have noticed that with the sennelier on PR satin, the 
deepest blacks still smear.

Anyone done this with polymer varnish? Do I just need to let my 
prints dry longer? I had a PR satin print that was 10 days old and 
applying polymer varnish directly on it, it smeared.  Is this more 
to do with the coating on the satin? Since I'm varnishing anyway, 
maybe just regular photorag is fine.

Sorry about all the questions. If you feel like taking a stab at any 
of them I would appreciate it.
