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?

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?

I see what you are saying however perhaps my use of the word PLASTIC instead of NYLON in relation to the seat is where the confusion has arisen :daumenhoch:.
BTW, I've seen loads of leaky carport roofs, they've mainly had holes in or been put up by a cowboy :LolLolLolLol:.

Right, i am not saying that "Dylon" does not work, it does, i have a Red Jaguar seat that is now Jet black, but it is only black on the surface and permanently so. 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.

All nylons are hygroscopic to some extent and as such are susceptible to deterioration due to moisture absorption. This moisture absorption also allows the dying process to work.

The glycol in brake fluid is hygroscopic and like nylon, is susceptable to deterioration due to water absorption (ie lowering the boiling point of the fluid)

which is why brake fluid needs to be changed every 18mnths
fu'ck we are a bunch of know all shmucks on here....lol
