Samples of your aircrte blocks...
As I have previously asked -- do you have any samples that you can send so we can have something to go by / compare our aircrete with -- to make sure we are doing this right?
I can send you an 8" x 8" x 4" block.
Paypal $25 to firstname.lastname@example.org to cover shipping and handling. I'll send it priority mail the next day.
