using future for the first time?

future is self leveling and should even it self out.  If you are getting a "grainy" finish you may have exposed flaws in your under coat.

Did you thin the future?  If so what did you use?

Did you use windex to clean your A/B (if you even used an A/B)?  If so did you clean out the windex with distilled water?  Windex wreaks havoc on future.

What Pressure are you spraying at?

Did you clean the surface before you futured?

Hmmm...answer these questions and maybe we can help you a little more!

 

Ant,

I am going to assume that you gave the model a primer coat prior to painting and may not have airbrushed your primer but used the rattle can type, if so you should have buffed it smooth prior to painting primary colors to your model. If the graininess is not visiable to the naked eye your OK, if it is then your going have strip it and re-paint it.  

yes i did use windex to clean the A/B, by what i have read this is correct?. after i use the windex i then give it a run through with thinner and make sure the A/B is dry before i use it again.

A/B pressure was 10-15psi. the test piece i did i gave it a heavy coat and it turned out really smooth and glossy and the decals went on pefect and the following coat of future was fine. i used the same paint on the test piece as the kit.

if it worked on your test piece, it must be your base coat. Future is real good at revealing flaws in your basecoat.

I used Future for my first time a few weeks ago. Airbrush, Don't brush it...I did, and it really showed brush strokes and it dripped and ran. Airbrush only )-I only use it as a coat for decals to go on and for canopies especially. Dipping canopies in future works best from my experience anyway. Good luck with what you're trying to do.

I seem to recall that Windex doesn't have ammonia in it any more, hence it's not very useful for thinning Future. I tend to use water or a drop of isopropanol.
