Back with round 2 as promised!

Okay so this time I got some packets of Grog SKI Booster powder, some green ball pen fluid from OTR, and some Steve Garvey. All of these are supposed to make your ink more buff-proof/ bleed through more layers of paint better (if you didnt already know this). I mixed these with MTN Street Ink and OTR Hard To Buff in every combination to see how it effected performance. I also tried mixing some ball pen fluid in with some OTR Flowpen ink, and tested a couple miscellaneous markers I had laying around, the Smash KO in green and the Might Marker Bleed-Through in Yellow. That one didn't even bleed through one coat, more of a joke.

The Grog products performed the worst in this test. The straight Street Killer Ink, even mixed with Garvey, and pen fluid did not bleed through the buff at all. I added these things to the Grog BPI too same result. I will say, the Grog BPI with the SKI powder and Garvey is one of the darkest blacks I've found. But it doesn't need through at all.

The Molotow Speedflow ink by itself surprised me. It's still visible a tiny bit by itself after 4 coats. The Molotow Coversal doesn't seem to gain much from adding stain boosters though. The coversal isn't very black, it's more blue. The speedflow dries with a copper sheen if you like that.

The MTN Street Ink has my favorite consistency. It took the Pen Fluid very well and just Street Ink Ball Pen fluid performed second best of anything in this test. Weirdly adding Garvey made it perform worse. Adding the SKI powder helped it a bit but it still did best with just pen fluid. The color with SKI powder and ball pen fluid is very nice too, dark sludgey green-black.

The OTR Hard To Buff wins again. With the SKI powder and Garvey added in, its a monster. The pen fluid made this one perform worse in terms of bleed-through.

For the strictly Steve Garvey add-ins see my last test. I did Black Krink Garvey in this one because I forgot to see what that was like in the last one. It didnt add much. OTR Hard-To-Buff plus Steve Garvey won that round by a lot. You can see it from the last test plainly still in the first picture, that was after 4 coats of Killz primer. I used 4 coats of kills primer once again for this test.
