Use protective gloves. The tip of my finger I used to apply Strike Hold went numb for about 16 hours.
Personally, not impressed. I cleaned a Beretta Tomcat with MP Pro 7, then lubed with Strike Hold. The action was slow and gummy. Cleaned again with MP Pro and used Gunzilla CLP; much smoother and proper action. Used Strike Hold on some magazines; still not impressed. The silicone cloth works better.
