Default 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?

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

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.

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