Question regarding slabs, oily specs and what not.

[Andy J.-migration]

Just recently began collecting slabbed books, and I was wondering about the ugly oily specs showcased on a few of the recent buys. Reffering to visualy annoying spots / specs / areas on the holders themselves, not the comics - oily, puddle looking areas.

 

Most of the time these are tiny and probably just a result of the process of slabbing the comics, but a recent buy has a big glaring area smack accross the front cover. Just wondering how common these slab "defects" are, and how much one should care

Is it like a flaw in the plastic? Not an actual substance on the slab, right? Is it like a gasoline rainbow shimmer or something?

 

How about a pic?

If it's the "gasoline rainbow shimmer" it's a normal thing that happens when the inner and outer well meet.

That's what I was thinking of, hard to describe really. Where's the OP to explain?

Well, it strikes me as somewhat different than the rainbow shimmer efffect, but its probably the same thing more or less. I added a pic, affected area is in the red square. Hard to spot on a snapshot, but its very visually striking up front. Sorta annoying cus it prevents me from fully enjoying this slab of a long time favourite cover! Guess I just have to deal or get another. So is this a common issue or a rare occurance?

What David explained is exactly what you are seeing. Inner and outer wells touching create that effect.

Ok, thanks for replying. I'll settle with that then
