Poly Fiber products very easy to use Ranthane finish looks good but is impossible to make a good looking repair. I was foolish to think I would never need to repair. Wind storm changed that thought.

The cans came double wrapped. Each can was wrapped in cadboard, sealed in a plastic bag and then put in a cardboard box. Everything came in excellent condition.

excellent product, however the last two deliveries, the cans were so dented up that the paint stores couldnt get them in the shakers to mix for me.

Second time Ive received cans of Poly Fiber products where the can was terribly dented. Concerned about potential leakage, I choose to transfer product to a brand new unused paint can purchased from a local home improvement store. Handling and packaging of these needs to be done more carefully.

Q&A

Q: What do you use to thin the poly-spray with?

Per the Poly Fiber How To manual, there are two reducers to choose from, R65-75 or RR8500. They are offered in quarts, gallons or 5G pails, and are listed as "Accessories" on this web page.

Q: Is this poly spray also a primer or do I still need to prime the fabric before I paint with either poly tone or aerothane?

Per Vendor, you would need to:

Step 1: Poly-Brush

Step 2: Poly-Spray

Step 3: Poly-Tone or Aerothane

Q: Is it ok to skip this UV protectant before painting with Aerothane? Bought a plane that previous owner said they skipped the UV stage to save money...

Per Poly Fiber, we do not recommend skipping this. It would be at your own risk.

Q: Can Poly Spray be used on aluminum as a primer for Poly Tone?

No you would want to use EP-420 epoxy primer. Poly Tone is not designed to be used on metal. Poly Fibers Aerothane or Mark II base paints are used on metals, over the EP-420 epoxy primer.
