Any one who has ever sided a shingled house has planed out the surface with 1/4" fan fold blue foam board. It simply lays over the high points and planes out the surface so you can side without the irregularities telegraphing thru. I had a heaved surface on the covered 3 season front porch on my house that had cracked do the setteling. To avoid the 1000's of dollars to tear out and repour the entire porch I simply added 3/4 foam to the surface and protected it with 3/4 tongue and grove osb and then indoor/ outdoor carpet. The foam will compress in the pressure points and remain full in the other areas. The added benefit of having warmer floors is nice too.
And yes it will weather forever !
