i read that post on crackle. doesn't sound like there's any single answer to getting that stuff to work. i thought the use of a gloss finish under the crackle coat had merit. a slicker undercoat would let the crackle contract more easily when it's drying. i'll give that a shot.
i sent createx an email last night to see if they make, or can make, a non-pigmented paint. not a clear coat but an actual clear paint. with that i could completely finish the color pattern, add the crackle medium and then spray the clear on the crackle. it should dry and crack and not affect the color pattern on the bait. no answer yet from createx.
here's the first crackle craw with clear coat. also put some bronze glitter in the clear coat on just the sections. not too bad but can be better. you can barely see the crackle under the final paint coats.
