Welcome to Librarium Online!
I'm in a position to where i can purchase my friend's 2500pt t'au army for around 150$ because he just does not play it anymore, and it is fully painted, but I don't like the colour scheme. its the basic T'au yellows, browns, and orange, and i want to repaint it, its mainly going to be fore diorama use since I play SM and until the tau get updated, i just dont like them as they are, do i need to do anything to strip the paint off of them? or do i just re-base coat them and then start anew? and also, i'm looking to make them more of a stark white theme, you know skull white with accents of codex grey and mithril. would you suggest that on tau?
guess i'm not gonna get the help i wanted lol. i'll try painting over the paint thats there, i just dont want it to look too thick.
Generally when your repainting an army you strip of the paint first. The best way I've heard to do it is to submerge the models in surface cleaners (such as simple green in US or Dettol in the UK) for a day or two, then use an old toothbrush to scrape the paint off. It should come off easily. When repainting over already painted models the details tend to get filled with paint (or as I like to say, killed). Killed details are not cool, trust me.
Here are two guides for stripping paint: UK Guide, US Guide - They are both pretty much the same, just by differant people and using differant products.
For painting the Tau White here is a really nice tutorial by minus_t - How to paint White Power Armour. I know you're not painting power armour, but its a really good guide to get a good looking armour with shades to it.
I hope that helped
