Loose carpet lining on ceiling of cap

Any suggestions on dealing with a couple of loose spots (as in sagging) with the oem carpet lining? I was thinking spray adhesive but the products I looked at today only didn't have a tip to affix a tube (think WD40 can) to.

Thanks for any input

 

Swap spray nozzles for one that will take a straw/tube, poke a small hole in the carpet, stick straw in hole and follow directions on can. The adhesive will be thicker than a lubricant so look for something with a larger bore straw that wont clog as quickly. Also DAP makes some various adhesive that come with a straw or you could get a tube of adhesive that comes with the plastic pointy nozzle. You could get a syringe and put glue in it too but it'll take longer to dry. Plenty of options, just get creative.

 

Figured others have run into this - thx for the tips I'll post what I come up with. Its not that bad but short of scraping the whole liner out and starting with a new one, i'm sure there is some way to repair the spots that are loose.
