Cleaning models

I have a composite jet in white and I notice that the colour is going yellowish where fuel has got in contact with it. I polish the yellowness out, but I will only be able to do this for so long before I go down to the base coat. Any ideas as to how to keep the new look?

RE: Cleaning models

keeping a fresh coat of wax on the paint should give you some protection.

RE: Cleaning models

This problem occurs on full size white painted aircraft, and is caused by the turbine oil. No way of stopping the discolouration as far as I know

I have just switched to Mobil DTE light turbine oil (approved by Wren for my engine) & it is almost clear wheras the Mobil Jet Oil 2 I was using had the yellow colour. Does the jet oil have a dye for identification or is it the nasty chemicals that turbine oils have but the DTE light supposedly does not have?

Maybe a change of oil will stop the problem occuring in the first place.

BTW, the DTE light is 1/5 the price of turbine oil in OZ. - John.

RE: Cleaning models

I think you are correct. I am using Mobil jet oil, which has a yellow colour.
