Although this is marketed as a marine-application fuseblock, and has something of a cover, I would not rely on its being at all watertight -- but that's just fine for my application and maybe yours. In fact I just deleted the cover entirely for my situation.
I am thoroughly enamored of this piece of equipment and am recommending it to others in my MG car club. I will own up to the reason I find myself here... Original wiring of the car had coil and fuel pump unfused. When installing a new fuel line I screwed up and that metal fuel line had residual tension in it that caused it to jump into contact with the hot terminal of the fuel pump. Thus I smoked the wire and had to replace it. But I resolved to put a damn' FUSE into each of the many circuits, and I breathe far more easily now. It's a neat and tidy solution, far more organized than the multiplicity of in-line fuses that was my initial approach.
UPDATE: Its been more than a year since my installation. I am pleased with the fuse block. No corrosion. It was worth the money regardless of the sticker issue. I used a little sharpie marker to mark the stickers and it is starting to fade out and bleed now. I Took a picture of it when it was new and keep a printed copy with my tools on board and on my phone. Because its doing so well for me I bumped it up a star.
It was well worth the money and I still say if the stickers that were shipped with it were the same as the ones pictured then I would give it 5 stars.
