Welcome to the Bunnings Workshop community @zzsmidav. It's fantastic to have you join us, and many thanks for your question about repairing chips in melamine.
There are a couple of options that you might like to explore. The first would be placing a Special Order at your local Bunnings store for some Melamine Mend from CustomPine. The supplier is Australian Panels, and our team in-store can take a look to see if they can order a single vile. If a single vile is not available, you could try the Empire White Liquid Paint Marker. Alternatively, you could remove the current melamine from the top edge and iron on a new length of 21mm x 10m Melamine Edging White.
Please let me know if you have any questions.Mitchell
