Wumby Posted October 17, 2011 Share Posted October 17, 2011 I'll keep this short. Would mold release residue on a mini make RMS white brush-on primer difficult to stick? And then with another mediocre cleaning, be the cause for an unwanted "crackle effect" for the base coat? (I've already put the model in the simple green bath and will be re-prepping it this afternoon.) Thanks in advance for input. Quote Link to comment Share on other sites More sharing options...
joshuaslater Posted October 17, 2011 Share Posted October 17, 2011 Mold release can mess up primer and paint. Always run your models under some water and let them dry before priming. Some people will tell you to use soap, but I think the water does just fine. Quote Link to comment Share on other sites More sharing options...
Kormydigar Posted October 17, 2011 Share Posted October 17, 2011 I like to use a dish soap with grease cutting properties, hot water, and an old toothbrush to get all the recesses. Never had a problem with brush on primer after this simple step. Quote Link to comment Share on other sites More sharing options...
Angorak Posted October 17, 2011 Share Posted October 17, 2011 I would add to this that using an old toothbrush and some dishsoap under some warm water is even better especially on plastic or resin minis. And if you have handled the mini for a time even oil off your fingers can effect things. Doh...slow typing...lol Quote Link to comment Share on other sites More sharing options...
Wumby Posted October 17, 2011 Author Share Posted October 17, 2011 I did a simple rinse and pat dry, so I believe I'm going to double check after the SG bath and scrub with the toothbrush and soap. Thanks for the replies that confirm my initial suspicions. BTW, the crackle effect was actually quite cool looking, but out of place on my model.

Baphomet69 Posted October 28, 2011 Share Posted October 28, 2011 Yet if you ever find a mini the crackle effect would be cool for you'll probably not be able to reproduce it. At least that's how that sort of thing usually works for me... Quote Link to comment Share on other sites More sharing options...
Jubilee Posted October 29, 2011 Share Posted October 29, 2011 for the artist speed paint last weekend, I was behind schedule and primered the minis with some rustoleum spray primer. Apparently that stuff takes a really long time to dry and everyone's model's were crackling - the main culprit seems to be when the primer underneath is not fully set/dry before the paint is applied. There's also some chemical thing that goes on with some kinds of primer - which is one of the reason I switched from Krylon to Tamiya primer.
