I need to say that I haven't done any glasses yet...just flat or semi-flat items. I would think that compound curves would be a real challenge and this is where the sand blasting "silver backs" need to chime in with their tips and tricks. At least I hope they will! :-))

The way I tell which side is the slip is to scrap the surface with your fingernail; if it digs in, its the slip side, if it just slides over the surface, its the carrier side. This assumes 2 things, first that you have fingernails and secondly that the carrier side is the last of the film that you peel off.
Never tried the wet method, we use the hinge method which is to tape down one side, check your allignment, fold the resist back, remove the slip sheet and squeegee starting on the taped side. A plus doing it this way is that once the resist is squeegeed down, when you remove the taped hinge usually the carrier sheet comes with it.
Hope this didn't confuse you too much.

No, it didn't confuse me...I actually tried this but the mask got stuck prematurely in the wrong place and I couldn't correct it, so good bye to about 30 sq in of RapidMask. I'm sure the hinge method works well, but I don't think I have the dexterity to use it yet. The nice thing about the other method is that if you get it in the wrong place you can pull it up and put it down again. Once you get it where you want it, you simply squeegee the water out, blot it dry and blast. At least that's what my "vast" experience with this has shown me so far. I'd bet that most experienced blasters apply the mask dry, but I'm not there yet...

Am I understanding that there is a "wet" method to applying rapid mask?

Yes...basically:
1. Remove slip sheet.
2. Lightly mist exposed mask with water.
3. Apply to glass, move around as needed
4. Squeegee water out from under mask
5. Remove carrier and blast.
PhotoBrasive has a better description on this here:

Read down to "Alternative Application Method".
Don't do as I did the first time I tried this and mist the glass...that doesn't work. Mist the exposed adhesive side of the mask after removing the slip sheet.

You might try the vinyl application style.
Make your hinge down the center. Peel from one end and squeegee. Remove the tape and peel off the rest of the basking and then squeegee from the center.
This allows a good placement from the center with 1/2 the possible alignment error.

Harvey, are saying to squegee the mask AFTER the carrier sheet has been removed? I have tried this and it tends to tear the mask.....any ideas?

No. Do it as you are doing it now, but make the hinge in the center. That way it is more accurate and instead of working from one end, you have only one half or the mask to worry about at a time. It tends to help eliminate wrinkles also in the vinyl application. (I do some vinyl, not sandblasting.)

Try one of the firm "felt" squeegees - normally advertised through
sign suppliers as pin-stripe applicator. It is very good at removing
air bubbles and very, very gentle.

I'll see if I can find on. For now I have been using a rubber spatula.... typically used for icing cakes.......
Thanks.
