I have this paint and can't find more

[Michael C Henry]

I bought my cobra replica in Reno NV in 99.It came with this pint can of paint.I have used it all now and I'm having a time trying to get other brands of paint to match. The can reads "Glassodur Urithane Acrylic 21" written by hand is "88 Mazda 140 Crystal White (21M60)"I have left my hood as a sample for the local paint store to compare different formulas.The first two mixes wern't close enough .First can of paint seemed gray and the second mix was a cream white .I swear mine is an absolute White no black, red ,yellow, or the like.It is a single stage White Urithane and was poilishing and blending great untill I ran out.
I watched from a distance as they mixed batch.The first batch was from a formula from the mazda code on the can converted by their website.I swear I saw them add a few drops of black. That appeared gray when compared to my paint.They then gave me a small quantity of pure white to add.I added the whole amount of pure white and it helped but not enough. I went back and The paint store operator mixed a can and I saw her add a little red and what she said was a bright yellow.That made what I would call a creamy white. I tried a small area .That batch didn't match so in frustration I removed the hood and went back to the store with the hood. the store operator tried a mix , getting closer but not there yet.The store operator had given up on a the line of paint she was trying to use and went up to the higher priced line. They were used to basecoat and clear and I had a whole car in single stage paint. A call to the factory rep and it was converted to a single stage Urithane .Of coarse it was way more expensive and came with a hardener that was tempermental. She said the can of hardener would start to set up as soon as the can was opened. To try to prolong the shelf life I would have to clean the top with lacquer thinner ,screw the lid on as tight as possible, and store it in a refrigerator . And maybe it might last five weeks. Another employee came and got involved and other customers were starting to come in. The store operator went to help the other cutomers and the employee got involved in my problem .She then dug out the infamous scaning gun. and came up with another code from what we were doing before. The website was down that they go through to break down the mixes . I was there over an hour at the point when I left the hood. This working for a living sure gets in the way of things I need to get done.
