Ryan Posted February 3, 2020 Share Posted February 3, 2020 If one was to paint the rim first and then stretch the tire over it to fit, will the paint crack on the tire? Should you or can you primer these things before attempting? Thanks, Ryan 1 Link to comment Share on other sites More sharing options...
Wumm Posted February 3, 2020 Share Posted February 3, 2020 I would not usually paint vinyl tyres at all, due to the chance of the paint either cracking or reacting with the vinyl over time. I would expect that adding another layer of paint in the form of primer, would only increase the chances of this happening. S 1 Link to comment Share on other sites More sharing options...

krow113 Posted February 3, 2020 Share Posted February 3, 2020 Put the tire on. Liquid mask the tire with inert substance like PVA glue. Paint the rim. Use solvent based paint and seal w 50/50 IPA/Future. Demask by water soaking , fingernail peel. Weather with pigments. I have heard tis can be done , practise on the vinyl sprue. I think I would go about it that way. 1 Link to comment Share on other sites More sharing options...
1to1scale Posted February 4, 2020 Share Posted February 4, 2020 If you want to weather the tire, try using Tamiya pigments, they seem to stick pretty well to everything. 3 Link to comment Share on other sites More sharing options...
Ryan Posted February 4, 2020 Author Share Posted February 4, 2020 Truth be told I would like to paint the tire Tamiya Rubber and stretch over a pre-painted rim. No weathering on the tire. 1 Link to comment Share on other sites More sharing options...
1to1scale Posted February 4, 2020 Share Posted February 4, 2020 My concern would be the alcohol in Tamiya paint, maybe you can clip off a part of the tires Sprue and soak it in some alcohol, see what it does. 1 Link to comment Share on other sites More sharing options...
Ryan Posted February 4, 2020 Author Share Posted February 4, 2020 Yes valid question. I was going to hit it first with Tamiya Primer to seal them up. 1 Link to comment Share on other sites More sharing options...
Ryan Posted February 6, 2020 Author Share Posted February 6, 2020 Testing has commenced. Rubber tire shot with Tamiya Grey Primer spray bomb, then used Vajello Tire Black as final color. Gonna let it sit all day then see what damage I can do fitting it to a complete rim. Tire Test by The 3rd Placer, on Flickr 1 Link to comment Share on other sites More sharing options...
Ryan Posted February 7, 2020 Author Share Posted February 7, 2020 Tire test has failed, at first it seemed OK as the rim only scraped the inside of the rim. Tire Test by The 3rd Placer, on Flickr As I worked with it more I realized there was absolutely no adheasion what so ever, even the Tamiya primer flaked off like the sunburned skin of a Wisconsin spring breaker!

DocRob Posted February 8, 2020 Share Posted February 8, 2020 Pity, maybe you get some effect by thoroughly rubbing pigments in. Cheers Rob Link to comment Share on other sites More sharing options...
1to1scale Posted February 9, 2020 Share Posted February 9, 2020 There is something else you can try. In the automotive world, the same problem exists painting flexible plastic. They use adhesion promoter that grips to vinyl and urethane, and can be painted over. A car parts store brand is called “bulldog” and comes in a spray can. It’s not very expensive, so it might be worth a try. Link to comment Share on other sites More sharing options...
1to1scale Posted February 9, 2020 Share Posted February 9, 2020 I should add that the Rustoleum brand is cheap, the name brand is not. Link to comment Share on other sites More sharing options...
