Yea, HD didn't have the j-roller when I did mine either. I took a piece of 2X material and used some of the spray contact glue to adhere a piece of felt and used it. I could even beat on it with a rubber mallet to make sure I got good adhesion.
Greg, if you haven't done this, when you get both pieces properly covered with the contact cement, use some thin strips of wood, dowel rod, of even venition blinds that have been destroyed and taken apart. Anything that you can use between the 2 surfaces. Put the laminate down on the surface with these pieces between them, then you can move the top around to align it. I started in the middle, pulling a couple of the dowels out. Use the j-roller there to get good adhesion on that spot, then choose a direction, pulling a couple pieces of what ever you use out, and rolling from the part that is adhered to the part that needs to be adhered. This process will keep you from getting air pockets. Also, MAKE DARN SURE YOU DON'T HAVE ANY CHIPS OF WOOD OR OTHER TRASH ON EITHER OF THE TWO SURFACES!!!!! you don't have to ask me how I know that, just see my postings of my router table top. Unless you would like to countersink a penny into your table top too.
Be sure to do the edges first, then the top over the edges. Oh and let the piece be too big for the space and let it hang over. Just use a router and trim bit to cut off the excess. Not easy to do if the piece you are covering is stationary and you can't get to all sides. But scribe the piece you can't trim later to fit, then trim the other sides that you can get to. Hope this helps. Jim.
