Maximum adhesion to bare aluminum and steel Tempo's Zinc Phosphate Primers are recommended for priming bare metal. These primers provide maximum bonding to bare aluminum and steel. Tempo's Primers have been the workhorse in the aviation industry for many years.
The A-701 Yellow and A-702 Green Zinc Phosphate Primers meet the performance standards outlined in Federal Specification T-P-1757A. They also exceed the 800 hours of salt spray fog test (ASTM #B117). A-701 will replace A-901 Yellow and A-702 will replace A-902 Green.

Haven’t had a chance to try it yet.
A-701 Valspar Primer Yellow
Works well, no reported problems.
A-701 Valspar Primer Yellow
Great stuff
A-701 Valspar Primer Yellow
Perfect for repainting.
Good service.
Good coverage, quick recoat time, and less odour and toxicity than zinc chromate and other self-etch primers. Paint does aerosilize resulting in overspray “dust” on surrounding surfaces, so be sure to spray in well-ventilated areas and cover up flat surfaces in the immediate work area.
worked great, good coverage
Working great for touch up of my Beechcrafts OEM corrosion proofing.
No issues spraying. Convenient and did the job.
Good coverage, no clogs, made sure to shake for 2 mins and used at 84 degrees. Expensive to ship tho

In the past Poly Fiber has told us to only use Poly Tak over epoxy primers, so I would say no, unless Poly Fiber tells you something different for your application.
It doesn't say in the instructions, but in general, an acid etch primer like this does not require it to be a solid color, just coat the material and it will etch it.
This is a self etching primer and intended to be used on bare metals. An etch is not needed.

This is a zinc phosphate self etching primer. It does help adhesion, but more commonly used for corrosion protection without a top coat. commonly used on aluminum interior parts.
We are unaware of any other difference besides the color. We sell twice a much of the green than the yellow primer.
Per the supplier: This will depend if the surface you are planing on putting this product on is smooth or rough. If the surface is rough, then a light sanding will be recommended.
Correct, as per vendor, this seems to be more of a personal opinion. If the surface is smooth enough with no rough spots then it would not need to be lightly sanded. It will only needed to be lightly sanded if what you are spraying the primer on is rough, to sand down the rough spots to make it smooth.
Per the supplier: This may be depending on what the weather conditions are like. Please review the tech data sheet which is linked in the "Documents" tab of this web page for more information.
