Dielectric grease used to be the staple to lube stabs. Some people still prefer it as it's thicker and can last longer than 205g0 on stab wires. It's also much more affordable. 

• 5ml/5g of Permatex Dielectric Grease
  
• Comes in a syringe for easier application (does not come with fine tip point, grease is too thick to come out of that).
