DIY radiator repair?

I have an aftermarket aluminum radiator from a previous owner on my Elise, I'm almost certain it is from wizard cooling based off measurements. Im still trying to figure out exactly where. but it has a small pin hole either on one of the cross pieces of the core, or where the cross section mounts up to the end caps. I'm wondering if I were to find it is there a decent DIY I could do, or if it has to be welded. Also if it has to be taken to a proffesional does the cost of the repair usually come out to about the same as just buying a new one?

You can epoxy it. Many radiator shops just use epoxy nowadays as well.

I have several thousand miles on an epoxied one in one of my cars with no issues.

What kind of epoxy do you use?

Someguy, one trick to test (find leak in) radiator is to cut bicycle inner tube; clamp each end to radiator and fill with air.

Uh, don't forget the cap.

05 elise (BOE Rev300 supercharged, SSRs, shift tower mods, Multivex; HID hi/low beams); 05 Corolla XRS. Past '72 Elan Sprint (I restored), Lotus 7 w/X-flow, TT Supra, Bugeye Sprite, BMW 2002 & 2002tii, '65 GTO.

I think there is a special epoxy for just that purpose, but I have used regular 5 minute epoxy twice with no issues.
