BlackShell - Stop Rust, Corrosion Preventive Coating - Gloss Black, 1/4Pt

We purchased a previously owned home and the metal door needed updating and we didn’t want to replace so after several attempts at repainting this was the only paint that worked to prevent rust bleed through. It is expensive but better than buying a new door. I just wish I could have found it in red🙂

Expensive but worth it used on a 12’ open trailer and did some wire wheeling light sanding and prep work to the frame after taking old wood bed off and this rust bullet black shell did the trick applys easily with a 2” brush 2coats did cover quite a bit of area when dry looks like a powder coat finish did the project outside to have good airflow would recommend this for a dyi fix to any old steel frames

Good product, great protection

Easy to use, cleans up with water. It will leave brush marks. Covered the rust. So far so good.

Initial review (update at the end): This is my first time using Rust Bullet and I am pleased with the results so it won't be my last... BUT... It's difficult to work with. It is extremely tacky and begins skinning almost immediately. At first I thought they might have sent me an expired quart because as soon as I opened it, it began to expand into a thick foamy mess that started to spill out the top of the can, but I quickly went ahead and poured some out, mixed in a bit of solvent, loaded it up and went to spraying. The results... Really really good. I sanded using the suggested 80 grit and did 6 coats, the adhesion and hardness is amazing. The color options (white/black) do mostly limit it as an industrial paint as even though you can add a different top-coat the Rustbullet makes for a super solid top-coat. UPDATE (08-25-24) I've been repainting a bunch of jobsite boxes using this stuff so I thought I might expand on my review. Even though the results were good for the initial quart I ordered, I do think that first quart was past its expiration date as the paint I've ordered since has been of typical viscosity, hasn't foamed-up/skinned and has been easy to work with. A hardner is probably rarely warranted with this paint as after 24 hours it seems around 70% cured and by 48 hours it is 90% cured and is rock-solid. But with that said this product does not store wiell and should be used immediately after opening; I've been using the pint-sized to spray the jobsite boxes (spraying 5:3) and doing ~5 coats on ~25 sq feet before it's been depleted.

WHAT A WASTE OF MY TIME! I actually was excited to try this product, but this turned into a total nightmare, (see pictures) I could not get the lid off! This 1/4 pint sized can would go straight in to the trash if I hadn’t decided to send it directly back to the manufacturer! Let them open it!!! The label literally says “open with caution, contents may be under pressure,” what does that mean??? that hardly matters when the thing won’t open at all. The rim is deeper than a normal can, which makes it almost impossible to get any leverage. And the rim bent everywhere so it makes it even more impossible to pry open. I kept trying, and instead of opening, the lid just started bending and warping. I spent 30 minutes fighting with this thing using anything I could find. At this point, the lid is mangled, I still can’t open it, and I’m not about to force it and risk the paint exploding everywhere. Come on guys!!!! Worst design I’ve ever seen. Ridiculous!!!! ZERO STARS!!!!

This stuff is incredibly durable. I've used it on several different projects and it's held up remarkably well. The best test was using it on my mower deck. After a full season of cutting grass, it was still in great shape under that mower deck.

Awesome product for killing rust spots and 2k urathane primer work great with it no reactions

Easily covered 8 rims with some product left over. A few thin coats built up a nice hard finish with a good gloss. The product does have a bit of an oder so definitely work in a well ventilated area. Hopefully the finish will stand up better than products I have used in the past...time will tell.

Great product, putting on a thin layer as instructed. Small can goes a long way, and dries hard.
