The set I bought from Cyclomondo had a head badge (which I didn't need so I stuck it on the back of my Honda Civic that transports the bikes.) They went on nicely and have stood up for a year, still look like new, which is more than I can say for the originals! They are thin enough that they don't look "stuck on" even though they are. They can be clear-coated but don't need to be.

To enforce the spacing of the P I N A R E L L O lettering, the decals come covered on the "top" side with clear plastic surgical tape. The idea is that you peel off the backing then press the whole thing, tape and all, down onto the prepared (soapy water) frame surface. Then when it dries and is stuck firmly, you peel off the adhesive tape to leave the letters behind. I found I couldn't make this work: the adhesive tape didn't want to curve to fit the frame tubes and wanted to pull the edges of the letters off as it sprung back flat. Perhaps wrapping yards and yards of twine around the decal to hold the tape (and the decal) down firmly would have worked. But I just took the letters all off the tape and set each one individually into place, which took a lot of fussing and measuring but came out OK.
