vallejo game color

used alcohol once and turned into gummy and gooey paint

No joke there. No alcohol in Vallejo. You aint gonna like the result! I use acrylic paint thinner from MM and have had no problems at all.

Alcohol is a no no with Vallejo - as has been mentioned. I use, and have gotten good results, either Vallejo thinner or liquitex airbrush medium. I've heard that both Testors and Tamiya thinners also work well. I've also heard that Future works well as a thinner for these paints. And last but not least you can try some distilled water.

And your English is fine. :)

Alcohol will turn Vallejo paint into a mess. I wouldn't use Future as a thinner as it's also used as a varnish and will gloss everything up unless you also start adding Tamiya's Flat Base. Water works pretty okay. Vallejo and Tamiya both have acrylic paint thinners.

The best product I've seen is Windex. I just started using it last week and it works brilliantly. en.wikipedia.org/.../Windex

thanks all 4 the tips, i used windex and the results were good, sorry about responding so late

yep tried windex and it diluted vallejo excellently,  also sealed it off with future polish and a matt  laquer spray @ the end, seems ok
