Hi-Tek bonds really,really good on my acid cleaned bullets.
I tested on white ones with a little more diluted Hi-Tek solution. (Hot weather,I add denatured alcohol for a thin coat. Also more acetone than the instructions say.)

This is the first coat. You need a knife to scratch it,it's kinda "inside" the lead surface. I get very good second/third coatings on this. A separate Diluted First Coat Bottle is a good idea.
Everyone doing WW should test a bullet or two in acid (or even bleach like I did at first.)
It's hard (for a beginner) to judge the quality of bonding itself. I started with good looking but badly bonding,contaminated bullets at first. Now I'm just amazed, I will check all my alloy ingots soon.
