Xander,
I agree with using Neo Meglip. For years I used Liquin and was very happy with it. Then last year I got a sample of Neo Meglip and I loved it. It is now my medium of choice, and really should be tried if you can get a hold of some. Perhaps you can contact Gamblin about getting their products in Manila. Their website is
www.gamblincolors.com. At the very least maybe if you explain your situation they would be willing to ship you some.
