does anyone know if you can put epoxy on a resistor?

check the epoxys resistance. if it is lower than the resistor then no

Well yes it's phisically possible

but I think it might heat up too much and break something i'm not sure though.

I don't know how much resistance my 5-minute epoxy has but the resistor is 10ohm's

check it with a multimetre

I'm willing to bet you could, since it's basically a plastic when dry, but it doesn't hurt to check it

As for the heat of the resistor, make sure it doesn't get too hot, although I don't think that will be a huge deal.

resistors dont usually heat up so it should be fine

If it is a low wattage resistor, especially one that carries a lot of electricity, it can burn you.

Ok, I really don't think epoxy conducts electricity, let along resists, unless your epoxy is dumb, and is laced with metal.

Epoxy can withstand 200 degrees before melting. I have even seen some that is up to 400. If the part you are gluing gets that hot, then you have a major problem

And it does not conduct electricity

ITS PLASTIC!

Yeah the resisitence is most likely very high compared to the resistor.

There are conductive, metal-filled epoxies available. Go to an Ace hardware or your local equivalent and really look at what's in the glues section. Anything that comes in 2 parts is probably an epoxy, and if it names any kind of metal in large letters on the front, as in "ACME Aluminum Repair" for example, is a likely candidate to be conductive. A very popular general-purpose brand is J-B Weld and J-B Kwik, both are metal filled and should not be used directly on circuit components. I use them a lot on other projects because they are strong, machinable when cured, and high-temperature resistant. I used J-B Weld to fix mom's ceramic jar candle topper, it sits as little as 1/2 inch from a candle flame for hours at a time. Also, if it comes in a clear dispenser or tube (like those double syringes), and you can see that one part looks dark gray, black, or silverish, you can avoid it because it probably has metal in it too.

Aluminum epoxy, eh? That would be great for glueing heatsinks to an N64 chip. Heat conductive and high temp.
