Supplies and brands

I keep hearing people using the masking tape and CA glue trick instead of clamps, and my clamps are starting to look like they had a run in with Shredder, so l]my question is this: Where do people go to buy their supplies for things like this trick? buying a 3 oz bottle from Home Depot/ Lowes seems it would get expensive quick. Also is there a preferred brand (other then Blue Loctite)? Thanks.

If you are just engraving … this might be another alternative …

I just use 3M blue tape and cyanoacrylate from the dollar store. Works fine for me.

You might want to get a bottle of accelerator too.

EBay or Amazon.
