I ordered one of those little 2 oz. bottles of PaleoBOND penetrant stabilizer to try out on a small rib fragment that's pretty fragile. For anybody who also uses this product, how are you supposed to open the bottle before attaching the microtip? Do you just use a pin or something to puncture the little "nipple" that the microtip slides over? Also, once opened, does the microtip or the the bottle have to be sealed between uses so that it doesn't clog up? I only got a few microtips with the bottle so I presume that they are are supposed to be re-usable. Sorry to post this here but I cantacted PaleoBOND directly and they haven't gotten back to me yet. Thanks!
