Thank you for your support Graham
I apply bumps several times when The mold is closing but there is still the same issue. It has never happened when i use NR compound
It has pattern on both sides. The other side’s pattern is smaller and rarely the scars appears.
The pattern on my first post is on the top half
Please find the attached picture for its both side...
