Good Fitting Carpet Suggestion

Heat gun on the back side will help it mold to the pans. Just be careful not to hold it on there to long or hit the front side as the carpet can melt. Also contact cement in the areas with deep contours will help. Coat back side and floor and allow it to tack up before you lay it down.

Good luck I have fought many carpets over the years and it takes patience and strength to get them to lay down well.
