Dear K.Peerakiat, K.Achara,
From my point of view, we have to maintain the current condition (painted parts) to customer, FTT as it is. The thing we have to do here is to find out solution to make parts painted as usual.
My idea is to let ZPT to hire TCMA for painting before selling out to supplier. The actual work will be continued as it used to be (ZPT W/H send parts to TCMA Paint Shop and then return to ZPT W/H). However, there will be the additional document for hiring painting work only.
Anyway, anyone have any other idea, please feel free to inform by return.
Best regards,
