If your doing this at home,use a pen or marker.....On the road,spit and finger...
If you look real close when you add the glue,it will show you the hole.
You let the glue dry before the patch,you'll have a hard time taking it back off.
Don't know if you have ever used laminates on wood with contact cement,same thing....You get one shot,it better be in the correct position.
