ONREVA Tool Box Foam 2Pack 48x24x2 inch, Foam Inserts for Cases, Polyethylene Tool Foam Sheets, Drawer Liner Foam, Toolbox Kaizen Organizer and Storage Tool Shadow

This is good shadow boarding foam. I've seen several reviews for this manufacturer complaining that the layers are stuck together and that this was a problem, for me, I wish the layers were bonded together even stronger. The layers are meant to be peeled apart at the depth that you like and the adhesive the manufacturer uses allows for this if you peel the layers away properly. They actually peel nice and clean if you take your time, which leaves the surrounding layers intact, making for a really clean look. Sometimes the surrounding layers would separate and I used spray adhesive to re-bond them. I probably could have gotten away without using adhesive to re-bond the foam, as aesthetically it looked fine, but I made the fit tight and I didn't want to risk pulling up the foam and disrupting surrounding objects every time I removed the offending object. I'd say the layers being glued 100% is a positive, not a negative, don't be afraid. If you take your time with the initial cuts, the pieces you pull out can even have layers removed and placed back in to achieve the appropriate depth(s), so you can play around with variations, no worries. I used a little heat (be careful...) to get rid of the slight fraying and ended up with laser clean looking shadow boards and none of the poor looking torn up bottoms other people had when removing layers. The foam is also proving to be durable, so I have no doubt it will hold up well.

Worked as expected. I used a long new 0lfa blade. It cut just fine.

Order came fast works exactly as I expected

Although the foam is high grade after the first black layer nothing else peels correctly, I now have to use a soldering iron to shape the foam in order to save the 180 I spent on these 4 blocks

Being an aircraft mechanic you need to be able to inventory tools quickly. This really enhances that process.
