What is the weight of your cloth?

How may layers did you apply to get it that shinny?

Thx in advance
The basics of foam finishing technique I got from this thread:

The steps are:
- Two layers of lightweight spackling with 600 grit sanding
- Two layers of WBPU with 800 grit sanding
- Acrylic primer (optional)
- Acrylic paint
- Two layers of high gloss WBPU with 1200 grit sanding

On that picture it is shinny because WBPU is wet. It's the second layer. When dry it is flat but silky smooth.

There is an unexpected problem... even after two layers of spackling and WBPU there are still some pinholes left. I am thinking of altering this technique by adding one layer of 00 silk span (12g/sq.m.) after spackling. This will take care of any pinholes.

As far as weight so far I added 2 gram to the tail section. Pretty much nothing. It it somewhat time consuming process but very relaxing and rewarding.
