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.

Well please explain to me if they are not porous just how do they change colour when dyed using Dylon Multi Purpose Dye?

Paulo:
Why not see if you can get some Dylon "Grey" and just re-dye it.
Hot Water, lots of Salt, Grey Dylon, leave for one hour and should be good as new!
Paulo:
Thanks Diesel. I tried Dylon's grey on a white seat before buying this seat. It just didn't work. Totally screwed up the seat. :LolLolLolLol:
To be honest it's put my off a bit as it's seams a bit hit and miss.
If I could guarantee it wouldn't screw up the seat I'd give it a shot. :-[
TwoBobRob:
Now then...... here's an idea if you're feeling brave ;)
People on another forum I look on have a way of bringing the colour back to their plastic van bumpers. What they do is gently hold a hot air gun to the plastic. Not so much that it melts, but enough to get it very hot. Brings the colour right back I'm told.
They do this to old faded bumpers and I've seen some pictures, it appears to work a treat.
Don't hold me responsible for your fooked seat though eh? ;D ;D ;D

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?
