Jimh Posted July 16, 2009 Share Posted July 16, 2009 Just canvassing opinions and thoughts here. I'm told that it is "impossible" to get the same shade of semi gloss deep bronze green twice from the same company. Apparently the gloss is a BS colour can be replicated without variation but there is no formulation for the semi gloss variety because the matting agent varies. True or false? Slightly annoying because there is a Pioneer here looking like a patchwork quilt. :argh: Quote Link to comment Share on other sites More sharing options...
poppypiesdad Posted July 16, 2009 Share Posted July 16, 2009 (edited) I would have thought that there would be a recipe for the paint and would be easy to do Dulux ,Crown,Leyland paint centers mix all differnt types of paint daily , on a job i got Gloss ,Masonry and interior emilsion mixed to the same shade for the customer without any differnce in tone and this was for a shop front . Bronze Green is also in the BS 318C (British Standard) colour range so the colour should be the same whichever paint factor supplies or mixes it. Go with the same supplier like Marcus Glen etc and the paint should match Jamie any reason why we cant use dulux paint metal paint Edited July 16, 2009 by poppypiesdad Quote Link to comment Share on other sites More sharing options...
Stormin Posted July 16, 2009 Share Posted July 16, 2009 You're correct. Although the base colour (gloss) is the same the shade tends to vary once the matting agent is added. Very hard to match two different batches of matt or satin paint. The solution is to get a large batch mixed and split into seperate tins for long term use. This is what the larger suppliers can manage in the commonly used colours, just look out for matching batch numbers. Smaller suppliers or less common colours lead to shade variations. The other ideal is to do a finish coat to the vehicles all from the same tin. Quote Link to comment Share on other sites More sharing options...
gritineye Posted July 16, 2009 Share Posted July 16, 2009 As Norman says you are correct, when restoring period properties where a high gloss looks wrong this is often a problem. Many of the specialist "period" paints deteriorate quickly in my experience and although these are often specified, I have found the best thing to use is acrylic gloss. This dries to a "softer" gloss and looks much more in keeping on older jobs, as does an acrylic off white. It will mix correctly as no flatting agent is used, but understandably you may be wary of using it on a vehicle that you have already put so much effort into.

ted angus Posted July 16, 2009 Share Posted July 16, 2009 I used Deep Bronze Green gloss off and on throughout my time in the service. I have used it since when restoring my Gipsy. The main problem is it is a very unstable colour; unlike most colours that fade DBG darkens. before painting my Gipsy I had the tin tumbled for over an hour at the paint shop at Leuchars I sunsequently spent ten minutes stirring using a battery drill before decanting a quantity to use in the gun, The finished job was great . after just a few weeks some half wit damaged a small area on the front wing. I prepared the area primed undercoated feathered the joining areas, got the lads to tumble the can, then stirred it at home then sprayed the area. on drying it was a totally different colour . 18 months down the line the whole vehicle is even darker and the patch repair is less obvious. Sadly even when purchasing products to BS 381c the fresh from the tin shade does vary between suppliers, Whatever you are painting buy enough for the whole project plus 50% from the same supplier. that way you will slightly nullify tone changes by buying from either 2 different suppliers or 2 batches from the same supplier. There is no difference in colour between Matt semi matt satin semi gloss gloss high gloss and very high gloss of the same spec number, its merely the difference in reflectivity that is different and therefore the eye is fooled into thinking its different colours. good luck TED Quote Link to comment Share on other sites More sharing options...
Nick T236 Posted July 16, 2009 Share Posted July 16, 2009 I paint cars for a living, and paint my own 'green machines', and matt and semi gloss paints are a problem, as prevoiusly stated. Top tips:- 1. make sure tin is well stirred. 2.Make sure all tins are the same batch number.3. Try to make you have bought more paint than you need and, ideally keep in one air tight tin. 4. Make sure that when you thin or and add hardener that the ratios are always the same, a paint or mixing cup will insure this,[paint supplier].5. Ensure that you leave the same time between coats when applying the paint. 6. Keep all coat even when painting[ don't overload one corner, and apply not enough on the other].7. Air temperature can also be crucuial to the matting affect,and somtimes colour[ do not paint on a boiling hot day, and then paint the adjacent panel when its very cold, or damp].8. this war time paint changes over time[no U.V. filter in it I suspect] if repairing an area, be prepared to paint a larger area than you think.[fade out thinners works well for losing the edge of repairs] Hope this helps, Nick T236 Quote Link to comment Share on other sites More sharing options...
Jimh Posted July 17, 2009 Author Share Posted July 17, 2009 Cheers for that. There's an important lesson learned. Quote Link to comment Share on other sites More sharing options...
