I want to keep it that colour. I've been after a grey seat for ages. I tried dying a white seat but just didn't work.Would moisture ingres look embedded? How does hot water help?
Can i just say that plastic is NOT porous, dont know where everyone is getting this from, its on anything to do with a tuff question or dying question. By trade i am an injection mould tool maker ( anything plastic is made from a precision engineered steel mould ) So please believe me when i say i know this to be true. The only thing that will happen when putting seats, wheels, whatever in to hot water is that it will grow a little but once cool go back to its original size, and if its thin plastic it may distort it a little and that is permanent, but it will not soak in water.

It dont Dye all the way through its only on the surface, its a little like permanent marker pen when used on plastic/nylon it only on the top surface.See for yourself, next time you do some dying stick a bic pen lid in as well, when done get a stanley knife and cut it in half, if it was a blue lid to begin with it will still be blue on the inside. Plastic is not fabric, i dont see many carports with plastic corrigated roofs weaping water, do you?

And as for nylon being hydroscopic... i dont think so, brake fluid is hydroscopic and the resovoir that you top it up with is made of.... you guessed it nylon.
