With reference to my previous post of my attempt to seal the waterslide decal, I couldn't make it as good as the Japanese pro done it. So tried to do it differently this time by doing it in the following sequence.
1. Spray Character White (Semi Gloss)
2. Spray Mr Color Clear (Gloss)
3. Apply decal with Mr Mark Setter
4. Spray Mr Color Clear (Gloss)
5. Spray Mr Color Super Clear (Flat)
The result of the above is much more acceptable despite the fact that I could still see the edge of the water slide decal. The reason for me to say acceptable is because in comparison with the result of my previous attempts, looking from a certain distance and from certain angle, the decal will look as if part of the body; whereas the decal in all my previous attempts would look more horrible no matter how it is viewed.
I tried to use Mark Softer instead of Mark Setter in one of the experiment, and it turn out exactly the same as well. So I'd try to settle on Mark Setter for now because I find that I've not used to Mark Softer yet because Mark Softer seems to be able to render the decal useless should it is not used adequately.
