Plascon Micatex SAHARA paint in 5L pots withdrawn from SALES?

I bought 120L Micatex Paint (Colour = SAHARA) a few weeks ago to paint my house. I need 3 to 4l to finish the job. I looked everywhere in Pretoria and Centurion for a 5 liter pot. Yesterday I was told that Plascon doesn't make 5L pots of SAHARA paint anymore, and that I have to buy a 20L pot. Micatex is a very good paint, and last for 10 years. What must I do with 17l of paint after I finish the job? Dump it?
