Nuthin but luv for yah Siavash_s_s...
Yeah, I know the problems with gumming up of abrasive blades... some work better than others on Aluminum. I forget which ones now... been WAY too long.
I used Acrylic glue to put together the reservior, so it just bonds to it and dries clear. Usually I just tack it together first... make sure everything is straight and then flow the glue into the gaps... it's like water so it works pretty well. I have thicker stuff, but that's for filling in really bad spots if you ask me.
As for the res looking clear... is it not clear from sanding or scratches? If so and it's open so you can get to the inside... you can use a torch CAREFULLY to "flame lick" the acrylic until it heats just enough to start glazing over. Then remove the heat... I've used that technique to polish up edges of pieces before.
Hope that helps...
