CX820Joe Posted June 19, 2023 Share Posted June 19, 2023 I don't have much of a display, just a piece of board on top of a piece of furniture- which I intend to cover with something more realistic- but I have noticed that the USK Deutz combine leaves wet looking marks on this board, but no other model does, is this just some sort of reaction between the rubber and this type of board? Always been curious why it's just that model. Quote Link to comment Share on other sites More sharing options...
Stabliofarmer Posted June 20, 2023 Share Posted June 20, 2023 I don't think it's a reaction between tyre and board Joe, more a bad batch of tyres. I have found the Wiese Deutz 6175 Warrior I have also has a bad batch and looking at photos I think it was the whole run of them that are slightly tacky to the touch and remain glossy/shiny looking. I assume its someone got something alittle wrong with the plastic mix when moulding, or a release agent reaction. From casting resin and rubber I have certainly found the more rubbery plastics to be more volatile/ loss forgiving if you don't get the mix just right.

CX820Joe Posted June 20, 2023 Author Share Posted June 20, 2023 I had one of those Weise Deutz’s with that problem James. The tyres on this combine don’t feel sticky though, they just seem to leave those marks. Very odd. Quote Link to comment Share on other sites More sharing options...
SirTainly Posted June 20, 2023 Share Posted June 20, 2023 It's oils coming out of the rubber. There are some sprays that work to stop this on softer rubber like latex, but not sure for harder compounds. Quote Link to comment Share on other sites More sharing options...
CX820Joe Posted June 20, 2023 Author Share Posted June 20, 2023 I am wondering if weathering the wheels with mig pigment and pva might prevent any more leakage Quote Link to comment Share on other sites More sharing options...
SirTainly Posted June 20, 2023 Share Posted June 20, 2023 Might work, give talcuum powder a try too. It'll was off if it doesn't have the desired effect. Quote Link to comment Share on other sites More sharing options...
