Hi Guys, Thanks once more for your kind and appreciative comments. My apologies for not responding sooner but the last few days have been rather distracting!
Silver - That's one awesome thing to say - From the outset, when I returned to modelling I was inspired by an ad in FSM which said something like 'Any more real and you'd be eating fumes' - I think it was a paint ad. For me it's all about trying to achieve a degree of realism so to recieve that kind of comment means so much - much more than winning any comp. That said - all the very best for the 12th in Seattle, I hope you have a successful time and agreat show.
Patrick - I began airbrushing using a Paasche double action with a side cup. This tended to get in the way at times so I bought an expensive (to me!) Iwata with a central top cup. Just after this someone at my club showed me a very similar 'brush which cost just £22 (about $35 I guess) - this had the small valve underneath for varying the pressure. I bought one just to see how good it could be - Believe it or not I have used nothing else since The Paashe still gets used for priming and sealing only and all painting is done with this 'Spraymaster'. It had (originally) a .2 jet which became blocked when I tried using another acrylic paint other than Tamiya. Having tried everyway to clean it including Ultrasonic I resorted to opening it with a very fine wire which turned it, I guess to, around .3. It's proved more than aceptable ( particularly the price!) - and has not yet let me down. I think the first model I did with it was the Junkers 52 and have used it ever since - the Iwata virtually redundant except for the very finest detail and thats usually only as a last resort.
One of the things I do do that I don't see referenced that often regards using Alclad (indeed any paint) and one which I believe raises the quality of finish considerably is that I always smooth each and every coat out using Micromesh 6000 with water as a lube. (The water has just a drop of washing up liquid added to about a litre to help break the surface tension)
Before I had this 'brush I sprayed Alclad at around the same pressure - now I have the pressure at a constant 40psi and vary it at the brush to suit. I think it's much better to keep the pressure lower than higher - that can lead to the paint drying before it hits the model leading to rough, dusty surfaces which can also come off on the fingers.
Hope that help some - I'm no 'expert', just someone who enjoys what he does and tries to learn off others where and when I can. I would like to do more but I share this hobby with two others - doesn't leave much time - As my wife says 'something has to go' but which one!
Regards - Tug
