Okay, I just received a power of the force two AT-AT, and I love it. The only problem is...the decal on the front is coming off a little bit. My question...What do you use to get the decal to stick better? I need some help because I do not want to add something too toxic or sticky (super glue) but nothing too weak that will not hold the decal on!!! Please help me...I appreciate it. Thanks in advance.
