RMweb Premium Crepello Posted August 10, 2019 RMweb Premium Share Posted August 10, 2019 Will thinners in the paint mix cause the 'glass' to fog? I'm planning to do an OO gauge Class 25 and would appreciate expert advice before I start. TIA. Link to post Share on other sites More sharing options...
RMweb Gold Right Away Posted August 11, 2019 RMweb Gold Share Posted August 11, 2019 Can't answer your immediate question, but you could always try acrylic paint thinned with water. 1 Link to post Share on other sites More sharing options...
RMweb Gold Mick Bonwick Posted August 11, 2019 RMweb Gold Share Posted August 11, 2019 (edited) Will you be using cellulose, acrylic or enamel paint? What make is the class 25? Edited August 11, 2019 by Mick Bonwick Link to post Share on other sites More sharing options...
RMweb Premium Crepello Posted August 14, 2019 Author RMweb Premium Share Posted August 14, 2019 Hello Mick, I normally use Precision enamels thinned with white spirit fpr my weathering. The Class 25 is a Bachmann model. John. Link to post Share on other sites More sharing options...
RMweb Gold Mick Bonwick Posted August 14, 2019 RMweb Gold Share Posted August 14, 2019 (edited) In that case, John, you will not have any problems with fogging. If you feel you want to be ultra safe then mask the glass before starting, but you could quite safely airbrush your mix over the glass and then clean up afterwards with white spirit on a cotton bud. There's an example here, albeit not a class 25: https://www.rmweb.co.uk/community/index.php?/blogs/entry/21575-a-land-rover-series-1-of-indeterminate-length-step-7-windows/ Edited August 14, 2019 by Mick Bonwick Blog link added. 1 Link to post Share on other sites More sharing options...
RMweb Gold Dunsignalling Posted August 14, 2019 RMweb Gold Share Posted August 14, 2019 If you mask off the area covered by the wipers, any fogging to the rest of the screens should add to rather than detract from realism. John 1 Link to post Share on other sites More sharing options...
Locksley Posted August 16, 2019 Share Posted August 16, 2019 I think white spirit does tend to fog clear plastics. I use Flory Models washes for clear parts, they're basically a clay suspended in water which is slathered on, left to dry, then wiped off leaving behind bits that you want dirty. you could also get a similar effect from pigments or pastels. I used Flory Dark Dirt on my Sentinel which turned out fairly nice. 5 1 Link to post Share on other sites More sharing options...

John Important mention of the wiper-swept area. Few drivers want to drive while peering through a dirty screen. After all, if they misread a signal, they will be the first ones to suffer any consequences! Try to ensure that part of the screen is squeaky-clean.
