Why-oh-why you guys try and use some esoteric products to create water.. lemme guess, oh right, valejo do some bloody good paints, so they are supposed to do bloody good water resin too right? mistake my friend mistake! valejo is a commercial company, they would issue anything working only one time over 2 to do some money. Games Workshop also manufacture the same kind of water with the same dubious effects.
never rely on stuff that is supposed to be modeller proof whenever it comes to scale water making, when they work they usually cost more than regular artist stuff.
You could have use even worse: Nimix water, the worst sh*t i ever came through in 30 years of model making.
Actually, valejo water is good for.. uh, very thin water coats? and even there it doesn't work much because as you say it shrinks. No valejo water is best left in some corner and never touched nor bought.
Now if you want to see the best ever product to do water I have ever used:
this Gedeo chrystal. My Galilée sea
is done with it. It doesn't stink much, it doesn't shrink and you can clean your brushes with water (they say) and it doesn't keep any half life after setting like polyester resin which means you can let children near your diorama (not TOO close!). Only thing: it's expensive..
But then looking at your pics I rather think the job is really well done, if i haven't read your comments I wouldn't have suspected some trouble brewing only from the pics.. Good luck anyway!
