THX Paul..
Not knowing the situation, I probably would go and spring for the UV version, which wouldn’t buy me what I need..
Where do I find “Jerry’s”?
TIA,
Eddie

Eddie,
I use the non-UV version of Lascaux Fixativ. The UV version is just like Print Shield and negatively affects the surface characteristics of the paper. Mark (of aardenburg-imaging.com) believes the thickness of the UV coatings is so thin that the protective effect is mostly from the reduction of the rate of oxidation. I agree. Consistent with this view is the fade testing results of the black ink. At partial load it's relatively weak. At full load, it's strong. With the very low viscosity Lascaux we're using acrylic to fill the coating instead of more ink.
I have been using 4 coats, one each with vertical, horizontal, and 2 diagonal patterns. It is probably best to allow drying between each coat. I sometimes use a hair drier to speed this drying, sometimes not.
I'm in California and can spray all year in my open garage with cross-flow ventilation. Wear goggles and don't breath. I have a respirator that I use for very large prints. Usually I just hold my breath during the spraying.
The concept here is to lock up the absorbent material in the coating but not disturb the highly engineered surface. Figuring out exactly how much Lascaux is needed to accomplish this is the problem. I don't have an answer there. (That is part of why I've switched the printer ink setup to increase the lightfastness, just in case the spraying was less than totally effective.)
Search for deals on Lascaux. Sometimes Jerry's will have a sale. I buy quite a few cans when that happens.
I have not done a lot of research on good and cheaper substitutes for Lascaux (non-UV). I found it via a speech by a National Museum expert to the pastel painters' association. It was one of the few 100% acrylic sprays he recommended. The others seem to be gone -- some acquired by large paint companies that may or may not have changed the ingredients. Lascaux has the original acrylic in it, which is non-yellowing. Many if not most of the sprays will yellow. I don't believe the ads on the cans after testing some "non-yellowing" sprays that yellowed in only 100 hours in my fader.

A Short while back Paul Roark mentioned the use of LASCAUX fixative spray for glossy B&W un-glazed EPSON CLARIA prints ..Paul, if you’re reading this, can you share your experience in HOW you use this protectant?..I’ve been using Premiere Art Shield Lacquer, and it’s GREAT for LUSTRE or MATTE finish media, but dulls the glass-like surface of the glossy papers, obviously killing the liquid look ..How many coats do you apply?..How long does it take to dry?..Where have you found the best pricing for this spray?..My internet search tells me this stuff is quite expensive..At least $25-$30 for a small spray can of the UV Gloss….My largest prints (12x18”) would slurp up a can/cans in no time.
THX in advance to PAUL and others that may chime in.

http://www.jerrysartarama.com/discount-art-supplies/sprays-and-fixatives.htm is one supplier that sometimes has good sales. (Almost everything is always on "sale" there.)
Dick Blick is an outfit I use a lot. See http://www.dickblick.com/products/lascaux-fine-art-fixative/
The spray I use is Lascaux Fixativ (or Fixative or Fixatif) 2070 -- the non-UV version. This is a solvent-based acrylic that penetrates the micro-porous surface of glossy papers.
It's expensive. It would be nice to find a good but cheaper substitute that not only was low viscosity, but also non-yellowing with a good nozzle.
Rohm and Haas Company was the source of the original, non-yellowing acrylic. That company is now part of a large American chemical company. That makes me wonder if they have a second product under a different name that is essentially the same. I can see them doing a private label through a large spray distributor.
The companies I'd trust most to sort out the qualities would be those that supply the pastel painters. Daniel Smith and Blick are a step ahead of Jerry's in their selectivity and knowledge. It does deserve some research here, as it's an important part of a really good glossy print solution. Locking a dye into the coating has a lot of appeal.
Note here that with some types of paper/coating, the higher viscosity sprays like Print Shield don't do that much "damage" to the look of the print. The thinner (slower to evaporate also) sprays that penetrate the micro-porous coating, like Lascaux are needed for my preferred Red River Polar Pearl Metallic. (I'm sure there are lots of metallic papers. This is just the one I use.)
