HI-Power Reblue help

[CETME]

I recently bought an Argentine Hi-Power, and the blueing is quite thin, i didnt pay much for the handgun, so i really cant afford to pay alot to reblue it, can i do it myself with the Perma Blue stuff that you can buy at walmart? or will that give me less than satisfactory results. any recommendations or advice? like i said, im on a budget... thanks guys!
