Vette(s): 72 t top 350 77,000 miles

I had a deer hit my 72 on front passenger fender, 

the mix ratio says 2% hardener, is there a rule of thumb , like 2 drops to a golf all size resin?

2% seems hard to guage

 

thanks

Vette(s): 1973 Orange Metallic Coupe (orig owner), L82, 4 spd (WR), PS, (A/C & PW (I installed from wrecked 73)), leather, AM/FM Stereo, ran with '65 FI unit earlier & will again some day. 2023 Accelerate Yellow HTC Stingray

Just looked at my can of Bondo and it says to mix the half ounce of activator to the 16 oz can of resin. Obviously you wouldn't want to mix up that much at one time but that should give you the ratio that you're looking for for that particular brand.

That's a good gauge , I can divide it for smaller.

thank you
