How many small star or rock crack repairs will a standard 15ml resin fix?

Question:

How many repairs will a standard 15ml resin fix? Speaking of small star or rock cracks

Answer:

I will assume you are using a Delta Kits Bridge and injector and are repairing small star or rock cracks.  Delta Kits recommends 14 drops when using our glass pipette dropper & 7 drops if using our older style plastic pipette dropper. (The dropper volume is different between the glass and plastic dropper) You must dispense the resin as deep as possible into the injector barrel when using in a top loaded injector as is the Delta Kits Injector.  Here is a link showing the correct application of resin into a Delta Kits Injector. Now back to your original question, by using the guide above you can expect a minimum of 50 repairs from a 15ml bottle of resin. Cracks are a whole other topic, no good answer for that, too many variables.
