I've just started reading these threads on doming...I'm wondering, is the regular epoxy that Home Depot sells different than what I would need for this? I've always considered epoxy something that you use as a glue...

Mike,
Epoxy resin, for doming, is different than those sold as adhesives.
Basically, there are two types:
1) One-part UV cure.
2) Two-part air cure.

Thanks David...I figured that, but wanted to ask to make sure...This sounds like a nice little addition to my laser engraving with very little start up costs added.

The difference between specialised doming products and generic water clear 2 part epoxies/urethanes is amongst other things , the resistance to yellowing which is a huge problem. Some cheap epoxies will yellow in a matter of weeks outdoors or months indoors.
Using it on something like a badge will guarantee you an irate customer a while down the line. There are inexpensive starter kits out there using good 2 part UV resistant urethanes supplied in carts , complete with a applicator gun and a static mixer. Thats the route you should be following.
If you have an inkjet printer , use inkjet vinyl (polyester based) and use your laser to kiss cut it , use the laser to cut the substrate it goes on and apply the decal to it , dome the whole thing. Let your imagination lead you to the variety of products you are capable of making. Even just doming the self adhesive laser die cut inkjet vinyl with a flexible dome for specialised stickers is a huge application.
