Gentlemen,I see thet vallejo recomends a 4 hour dry time beween coats of their varnish,be it gloss,satin,or matte.Is this really the case or can that time be pushed Thanks,Jeff

Jeff,

All manufacturer's instructions err on the side of caution, especially paint makers. How do they know whether you are spraying in a humidity and temperature controlled room (like I do), or a garage in Florida in June with 100% humidity? Even so, the manufacturer will recommend optimum times to allow their product to perform it's ultimate best.
That being said, Vallejo varnishes are excellent, and I have added an additional coat in as little as half an hour without it milking on me. I have also waited 3 days for my final varnish coat to cure before using other mediums on it.

Matt,Thanks for the answer,it's what I was looking for.Jeff

I use window cleaner as a solvent for them and if I apply it in thin coats, I never wait more than 10min.

what are your thinning ratios?Jeff

If I have to thin Model Air, (and varnishes I never do) I wouldn't use anything containing alcohol or ammonia. Vallejo thinner, Distilled water, or Liquitex Flo-Aid are the thinners to use for Vallejo products.

Wait a minute....Francisco, does the window cleaner you use have ammonia in it?

I was told ammonia products like window cleaners (Windex over here) did not work with Vallejo.

I'm intrigued....

Matt, I know you and others have said in the past (as you did now) that ammonia-based products like Windex, etc. should not be used with Vallejo. However, I have to say that I've heard from many who use that combo without issues. And judging by Francisco's excellent sub I can tell it works for him too. I'm at a loss on this one. I know I've tried using Windex with Vallejo Air once and ended up with a completely clogged airbrush but I can't understand how others make it work the way they do. What's the trick here?

Rob

I too have not had good luck using windex to clean out my AB after spraying vallejo.For me it makes a mess.Somewhere in another thread Simple Green was mentoined as a cleaner.I had some and tried it and it worked well.Jeff
