Painting
Begin painting.
At first, paint undercoat on EVA foam.
The effects are as follows.

-Color becomes well.
-It becomes hard to come off.
-Gloss comes out well.
-You can save quantity of the paint.


1.Gesso
This is easy.

【Merit】
-It's usable just to paint with a paint brush.
-Gesso don't contain thinner, then you can use it in the room.
-You can use also Acrylic paint.
-There are several colors one, white black etc.

【Demerit】
-It's easy to come off than Thinned "Bond G17"(one of liqud glue in Japan).
 Then, use this for weapons and armors without moving parts.
-The gross is smaller than Thinned "Bond G17"(one of liqud glue in Japan).

【Commodities　page】
Gesso or Black Gesso
or

【Paint】
Lacquer Spray or Bottle lacquer paint or acrylic paint
or

2.Wood glue thinned with water
This is so easy.

【Merit】
-Someone can get
-Someone can use easy

【Demerit】
-Drying time is a little long.

【Commodities　page】


3."Bond G17"(one of liqud glue in Japan)
This is dangerous method, it's most likely happening fire.
I wrote about this method as a archive,
However I don't recommend this.
I don't use this method now, I use other method now.
If accedents happens, it's self-responsibility.

【Merit】
-It'st hard to peel off.
-It can use for PVC pipe or plastic sheets.

【Demerit】
-"Bond G17" is japanese commodity. Then you can't get it easily.
-It needs thinner, then you must work outdoors.
-It burns easily.
Don't use fire until drying, because "Bond G17" burns easily. Don' use a Lighter etc until drying.
The parts will be charred in seconds.
