My 94 Camry's reservoir seems to have a few small holes in the top area of the reservoir. I know its not a big deal as the antifreeze will not come out unless its filled to the top. I looked at RockAuto and NAPA Online and they only have the gold plated ones for over $80.00. To me it looks like it should cost between $5 and $10. What can I apply to the small holes. Or focus my attention to other things that need to be fixed.
