thats not really a big issue :-) Another couple of questions any
experience
with alumaloy brazing rod you use with a torch? How effective is a epoxy
patch on a hairline crack and best ways to remove tar that bin applied to
the floor? I thank you in advance for the help :-)

Yes - dont' use the brazing rod - it doesn't work for crap.

That aluminum boat I mentioned earlier had a crack along one rib that
ran lengthwise for about a foot. I tried a few epoxies, sanding down
the area to bright, then using the filler, but it never worked. If I
had thought about it, I would have realised that aluminum flexes and
epoxy is fairly rigid - the two don't necessarily go together.

So, after much acetone and cursing, I finally had a welder with a TIG
get up just weld it. Lasted as long as I needed and last time I knew,
the boat was still floating and didn't leak. In my opinion, the only
way to go is to weld the crack closed - it's not going to cause a
major "brake" on your budget.

Tar on the floor? As in tar tar or a black substance? Is the floor
aluminum, wood, carpet?

If it's tar on the aluminum, use acetone - finger nail polish works as
well, but it's not a strong. If it's tar on wood or carpet, good
luck.
