I've finally found a white spray paint that matches my white tuflite board, for doing repairs.
The Tuflite-brand touch up paint is only available overseas and it's a pain to get it here.
I found this one matches pretty well:
Brand - MOTOSPRAY
says on can - "Quick dry - Super Enamel" - 400g
code next to the barcode on the can - "QD2001 Gloss White"
It's 5 minute quick dry between coats. The spray is super fine. Easy to use.
I got it at the the local auto store "AUTO ONE". $14.56
Hope this helps someone.
