Finishing Puppet printed with foaming TPU : Flocking vs. PAX (Latex/Acrylic) for a Beginner?

I am 3D printing a puppet head using foaming TPU (Siraya Tech). Due to stock issues, I’m using Black filament, which I now need to finish in realistic human skin tones.
Given that the TPU is flexible and has a matte, porous texture, I am torn between two finishing methods and would love some advice on which is more "beginner-friendly" for achieving high-quality results.

Option A: PAX Paint (Liquid Latex + Acrylics)
How hard is it to achieve opacity over black without the paint becoming too thick and losing detail? Is there a specific "white-out" flexible primer you recommend?
Durability: Does the porous nature of foamed TPU help the latex bond, or is peeling a major risk?
Application: For a beginner, is brush-painting effective, or is an airbrush mandatory for a smooth, non-streaky skin finish?

Option B: Flocking with fibers
Ease of Use: Is flocking "easier" than color-matching skin tones with paint?
Coverage: Since the filament is similar to a foam material , will flocking bind better to the material and provide enough physical coverage to hide the base color entirely?
Longevity: Does flocking hold up better than paint on a puppet that will be handled and moved frequently?
Colour: Can using flocking provide a range of vibrant, realistic skin hues?

If you were a beginner starting with a black, flexible substrate, which method would you choose for the best "effort-to-result" ratio?
Thanks for any tips or experience you can share!

    Pax paint should adhere well and hold up well.   I've never tried it on foaming TPU, but it should work.  I. would do a small test piece and see how it handles flexing and abrading.   It should cover the black in a couple of coats.  You can start with a heavy pigmented PAX as a primer.

    For flocking, are you talking about mixing flocking into your PAX, or flocking the surface to have a "fuzzy" puppet?

    Hi Chris, thanks for replying! I would try to get my hand on some pax paint and a pax primer. As for your question, Yes, I’m definitely aiming for that classic, fuzzy puppet texture, very much like Statler and Waldorf. My main concern right now is detail retention. The 3D print has some really defined facial contours and textures, and I'm a bit worried the flocking might bury or soften those features. Even so, flocking feels like the right move since painting has such a steep learning curve, and I really love that authentic puppet aesthetic.

    Alas I don't have anything to add regarding paints, but I'm real curious as to how the puppet handles materialistically, like with stretching?

    I've experimented with using regular TPU for skin material, and while it flexes well, it doesn't have any stretching/compression properties. Does foaming TPU work better? If you have an example that you are able to show, that'd be great!

    Flocking should work for your application. It would hide some finer details, but it's worth a test.
