This car is the custom model. My car is losing Freon in a matter of days. I cannot seem to find where the leak is coming from, used the dye to try and find the leak but nothing showed up. Any suggestions on where I should focus on looking for my model car?

Where have you looked?

I would say that the most common leaks that I have seen are from the A/C condenser where the fins might have gotten damaged from hitting something, from the various valves/seals/o-rings throughout the piping, or from the compressor itself. Personally I have seen several with the leak in the piping or the compressor leaking from the main seal.

Also, when using a leak detector, you do have to use a UV light and glasses to see the leak. I did not know if you knew that or not, but most of those leak detectors require the light and glasses.
