using setter will create silvering problems. I never use it. always use softer even on flat surface. if not use softer the decal will have wrinkle problem most of the time.
guys.. for those who still been confusing over the usage of Mr. mark softer and setter, let me say one more final comment.
Both Mr. Mark softer and mark setter are meant for troublesome
water-slide decal application.
Basically IF YOU DON'T HAVE PROBLEM with your water slide decal, don't trouble yourself getting it and get confuse over the usage different between the two.
All new water slide decal shall work nicely if applied properly WITHOUT Mr. Mark softer or setter.
PROBLEMATIC DECALS:
1) decals fail to adhere or keep lifting up after drying = Mark setter
2) decals fail to conform to complicated surface (raise area, panel line, hole, etc) = Mark softer
If you got silvering(patches that looks like mini bubble trap beneath decal), more likely the surface is matt/uneven/not gloss.
Make sure surface is always gloss and not matt before decal application.
NOTE:
Mark Softer is more potent and may cause your water slide decal to WRINKLE. This is NORMAL. Just leave Mark softer to do its job once applied, never touch until it's fully dried.
