Fast forward April 2019 to Jan 2023. We did swap the 08 YXL Denali for the 09 Escalade because the Platinum trim truck does have a leather covered dash, (4) door cards and console trimmed in high UV protected leather. Due to COVID we paid $1.2k more to swap because we bought low & sold high. To date, knock on wood, no cracked dash.
The company that GM hired to glue the leather on the dash, Dräxlmaier of Germany did so with a direct bond of contract cement on an OEM black dash. There’s no special padding or reinforcement. This is a job that can be pulled off by any upholstery shop without pulling the glass. Prep, repair and cure is the key to the existing damaged dash cap prior to leather overlay occurring or, obviously start with a new dash cap, the use high UV treated leather is a must.
