Not trying to be rude, but it sounds like a lot of smoke and mirrors to me. A case of "Emperor Goo's new clothes."

I'd be willing to bet that Liquidtex (or Lowes/HD paint department tints) could tint white Goo to acheive similar results as Gray Goo. My only concern would be that it might require adding drops of a few colors in addition to black to achieve the desired neutral gray. Most of the neutral N8 and N9 shades, are composed of drops of 2 or 3 different colored pigments added to the white base. If you could take a sample of Winter Mist, or another known OTS neutral gray into Lowes... along with a quart of white Goo base, they can measure it on the X-Rite color matching computer to determine exactly how many drops of each pigment is needed to to make it match the neutral gray shade you have a sample of. They (Lowes & Home Depot) have this function built into their paint mixing systems, so that they can add pigment to an existing can of paint (to correct the color) if they initially got the color recipe a bit wrong.

Not sure if I'd tint the top coat though. I'd speculate that Goo acheives some of its gain boost with the translucentcy of the top coat. I'd suspect that tinting the top coat would destroy its ability to increase gain. If their topcoat truly is grey, as one of the senior members suggested.... then maybe there is something to Goo's claims.

I'd assume that Goo only wants us to believe that they use a blend of unique and exclusive ingredients. If the public stops believing this... then nobody would pay Goo $120 for 2 quarts of paint anymore.

Of course, I could be completely wrong and this might very well ruin your Goo. However, it would be interesting to try it, if you had an extra quart of Goo. A half quart would probably work as well. You would simply have to have the Lowes employee reduce the drops of pigment suggested by the X-Rite for a quart, in half.

Your not being rude at all, different opinions and view points help us all to learn. But perhaps I'm missing the point on something, why would anyone want to alter white Screen Goo to try and make a grey coating when you can buy one of Goo Systems grey coatings that are ready to use out of the jar? The cost of the white and grey coating are the same.

I thought he said that he won the white Goo cheap on Ebay... and he was hoping to modify it to Gray, rather than actually shell out another $120 for the Gray version.

I agree with you. It would be easier to just buy the gray version from the get-go. It sounds like he's trying to make due with what he won for cheap in an Ebay auction. I can't blame him... If I scored the white Goo cheap, I'd probably want to tint it gray as well.

I did win some white on ebay but after doing some research (I was advised by several projector salesman to use a white screen with my Panasonic PT-AE4000U Projector) I decided to keep it white.

I then decided not to use it at all because I made the decision to buy an electric roll-up screen so I could place my 50" DLP TV behind it so I wouldn't have to fire up my projector to watch "non worthy" programming. (Those replacement bulbs are not cheap.) I purchased 2.3 L of Goo (Base & Top Coat) so I had plenty to experiment with, but I sold it for a little bit of a loss. Oh well, I guess someone else will have to experiment with it.

Note: ZMan was very professional and courteous when I spoke to him on the phone and I want to thank him for his help. I was looking forward to using Goo but my new plan was a no brainer once I thought through my options. It takes a lot of time to design the ultimate home theater, not that mine will be as ultimate as some...
