adherring objects in our camper

[kjchamberlain1]

I am looking for a clear like gel that is similiar to rubber cement that will adhere any object within the camper like a lamp or decorations securely so when driving it will not fall over, but can be easily removed without leaving a mark. But to no avail I am unable to find it on the internet. Someone told me it might be called miracle gel but when I searched I came up with zilch. Help!!
