After speaking with the tech at Speedokote, I purchased a pint kit of the Speedokote SMR-105p 2K clear. Pretty inexpensive at only $19.00.
It is a true 4:1 2K urethane with UV protection and the claim is that it can be buffed out in as little as 45 minutes.
If it is as fuel proof, durable and glossy as any of the other quality 2K urethanes out there, I hope to be quite pleased. I might try it with my cheapo harbor freight detail gun or thin it and run it through an airbrush.
Any thoughts from the 2K clear users out there?

Brent,
I read the tech sheet.
I would read the can and follow the reducing directions to the tea. Tech sheet says not reduce more than 5% but if you do an "Accelerator" MUST be added.
Be interesting to find out what happens if you reduce more than 5% and don't use the accelerator?
I said this once before, I think 10% is the max reduction recommended by "most brands" of 2 part clear urethane.
That product is a 2 part urethane clear and it should be fuel proof?
Wax will help.
One thing though, it does say that the product is "Specifically formulated for the mobile repair industry."
There are independent touch-up vendors who are contracted by auto Dealerships. Their tasks are to bring back to life small areas on vehicles that require paint repair.
Most of this work is on the front and rear bumpers and the painting of aluminum wheels. There's plenty of guys doing this mobile thing.
The wheels are generally an entire repaint but the bumpers require blending. This product "Formulated for the mobile industry" would be those guys.
BTW. These guys that do touch-up paint and frequent Dealerships know their product and have a good deal of ability. They can earn two grand a week with the right accounts.
So can a qualified pinstriper. ;D
Good luck with that product.

MOST two part products that I have sprayed have a specified reducer ratio. This ratio is devised in a lab to comply with EPA requirements for VOC emissions. THis typically will not have much significance with the performance of the product.
I almost always over reduce my clear when spraying a model. Several reasons for that including the prime one beig that we are spraying from a smaller nozzle and gun that the typical end user of the product will.
Without going into a long drawn ouot explenation, you can over reduce the clear with no functional reduction in performance. You need to reduce it so it will spray trough your equipment in your enviroment and give you the finish you desire.
Please dont get caught up in the trap, go ahead and reduce it to get it to spray properly.
as a caveat, you can over reduce it, but logic will generaly prevent you from going to far.

Thanks for the replies.
From the MSDS and data sheet, does anything stand out that differentiates SpeedoKote from any other decent 2K clear?
From my limited perspective and understanding of paint, SpeedoKote seems like your basic, good, fast clear. I am just looking for the standard set of attributes that one hopes for with a 2K clear. Durability, fuel resistance, gloss, ect. The small size and cheap price were attractive for experimentation purposes, also.
The salesman indicated that many of their engineers and chemists came from PPG and Dupont.

Really I cant determine much from the MSDS and data, I really question the buffing in 45 minutes, that is just crazy and against my sensibility, if in fact you can I wonder how durable it can really be?
The only way to know is to try, I wish you luck, if it works out it could be a great find for you.

Biggest thing to remember is that shine doesn't come in a can!
