    what type of epoxy?

    Ok so I'm building a scratchbuilt sff lanbox and I have a dual 120mm swiftech rad that I want to modify. I want to add a fillport/window into The top of the radiator. The end cap on the rad is brass I believe, I've already cut a big rectangle out of it and I plan on securing a 3/8" acrylic block to the end of it with a g1/4" port on it. So I'm planning on drilling a bunch of holes through the existing end cap material and epoxying brass 6-32 nuts under the holes so I have something to bolt into when I secure the acrylic top. What epoxy or resin can you guys recommend that can hold up to distilled water or premix coolant?

    Yeah they are all pretty much waterproof. They do however make marine epoxy, I would choose it in this case: http://www.homedepot.com/buy/loctite...l#.UD5ertaPWbQ

    Adding a fill port is super easy check out my thread: http://www.xtremesystems.org/forums/...d-Modification

    Thanks CrazyNutz, I purchased this Lepage Marine adhesive from home depot and it seems to have worked. I drilled a bunch of holes around the square opening i cut into the rad and secured nuts behind the holes with the adhesive. I was just planning on running a bead of silicon around the edge of the "window" to seal against the acrylic but I found this How to Make Silicon Oring And I also plan on using your oven technique to paint my radiator with white enamel paint. I will post some pics of the rad today or tomorow.
