Lifelike decals cracking. What do I do?

I clicked on your photo link and I have a few idea's.

1: Take a good look at the remaining decal's on the sheet. Do they have the Decal film printed over the decal ? I had a decal sheet that did not get the clear film printed over the decal's . and my decal's broke apart the same way your's did.

I believe your decal sheet is just Ink printed on the paper. No "Carrier Film" 

2: Your decal's may be old.  Decal's will also do this when they reach the end of their "Service life"

Either way, your best bet, is to remove the offending decal's and get a new set.

If you apply a wash over your cracked decals you'll only enhance the cracks ,they will be even more visable, like panel lines are after a wash.  I'm not sure that your decal problem is even fixable. You may have to remove the culprits and start over with better decals.

Thanks guys. I tried to post a pic of the decals on the model but it didn't pass muster. Not sure how you guys post pictures on here. In the meantime, any ideas how best to cover up the cracks? Is there a weathering technique that may work best? Like a lite airbrushed coat of something dark over the entire wing or some other strategy?

Eons old bottle LOL. 

Sorry my mistake. I meant Micro Sol, not Micro Set. Yes I use Set all the time.

I try not to use Solva Set. It will cause "wrinkling".

 

Been using it for eons without an issue.

It could be that the decal is old.

It has it's place, but IMO not as a normal process.

I have used the Micro Sol and Set and find it to be weak and not snuggling the decal like it should specially if thick. I do not go back and forth with the brush. I slip the decal in place, blot out then apply the solution and let it set up and I do not touch anything till dry. Then I will see if it needs further applications specially if bubbles get trapped which are punctured with a pin or the tip of a #11 blade then more solution is applied if needed.

My go to solution is Solvaset that is very strong but works like magic.
