Glue that you can peel back off?

I sprung for a new 68 Barracuda rallye bezel and am dismantling the old one and at some point whoever worked on it used this white glue that stays slightly malleable to where I was able to peel it off with my fingers but it was strong enough to hold everything in place.

Anyone know of a similar type glue? The old bezel held in some of the lenses with little melted plastic studs but the new bezel doesn't have anything like that to work with. Would be nice to glue things in place but not have it be completely permanent in case a mistake is made. Thanks.
