Just started using Vallejo surface primer black tonight and it's having a hard time in my AB. It seems to dry on the needle tip in seconds, i believe it comes ready mixed for AB use so after a good shake i just dropped some straight in the cup @ about 20 PSI. All seemed well for a few minutes then i noticed my airflow was going up and down and the end of the AB needle had a good thick coating, so i cleaned out and started again @ about 15 PSI but the problem continued! :

Am i doing something wrong? Do i need thinners? Is my air pressure wrong?

Not sure what else to try, im still very new to airbrushing.

[QUOTE="fubar, post: 69637, member: 10931"] Just started using Vallejo surface primer black tonight and it's having a hard time in my AB. It seems to dry on the needle tip in seconds, i believe it comes ready mixed for AB use so after a good shake i just dropped some straight in the cup @ about 20 PSI. All seemed well for a few minutes then i noticed my airflow was going up and down and the end of the AB needle had a good thick coating, so i cleaned out and started again @ about 15 PSI but the problem continued! ::) Am i doing something wrong? Do i need thinners? Is my air pressure wrong? Not sure what else to try, im still very new to airbrushing. :P TTFN Matt [/QUOTE]
