Silicone spray ok to use on Polybushes?

[SteveS]

not sure where to post this question.....

Does anyone know if it is ok to use 3 in 1 silicone spray lubricant around polybushes? I'm trying to find an annoying squeak on the rear axle and want to use it to identify what is squeaking. The can says ok to use on rubber and latex.

I recall that there are packs of lubricating grease used on polybush installs - what is that grease made of?

I'm using red rubber grease on my trailing arms i figure if it works well and lasts on brake pistons without harming the seals then it should be good . I can only guess it's silicone based ?

Edit :- just looked it up and the red is not silicone based , its vegetable oil extract or some such thing .

The bush makers say to protect their bushes from alcohol based products. Nothing else is mentioned. Silicone oil is very inert and stable and I doubt very much if there would be a problem.
