Actually Phil Florey reviewed Stynylrez and in doing that relegated approx 5 other primers to the bin.
Tamiya he did not but rated Synylerez the tops.
My thoughts on Stynylrez which I have used since it appeared.
1. An awful name.
2. An awful paint to clean up.
3. That is the worst.
4. It is as self leveling as I have seen in all the primers I have tried.
5. It sticks to plastic like no other primer . It impossible to rub off. (It still requires a properly prepared surface)
6. It dries to a very thin coat despite its glutinous look in the
airbrush cup. It does not fill detailed area such as panel lines etc..
7. It is dense. Very dense yellow the most difficult of colours will obliterate any colour with one coat. Used yellow over black (one coat) for propr ends.
8. It dries almost instantly. It is handle-able after 5 minutes or so.
9. It can be sanded after an hour. It sands especially with wet and dry to as smooth a finish I have seen. Transition between Stynylrez and plastic is perfect it does not flake or crumble. Will fill very minor scratch areas without a sink effect over the scratch.
10. It takes Mr Surfacer without any adverse effects which cannot be said for any other acrylic primer.
11 After refilling and sanding a make good coat with Synylrez over the affected areas will reveal a perfect finish. No marks of the filled area and none where the old and new coat meet.
12. Will take paint, Lfecolor Mig Ak Vallejo etc. within the hour.
13 Comes in grey black yellow grey and white. It is Acrylic/Polyurethene. Badger suggest using a .5 needle plus using their own
airbrush cleaner. It can be airbrushed and hand brushed. I use a .4 needle with success.
Sound just perfect not found any reason to suggest otherwise except item 1 and 2 above. None of the above is an exaggeration.
