Not only are they al applied differently, but they all need to be tried and tested depending on how much feather and how much hair your horse has. Experiment! One word of advice, sometimes using a lot of water is not the route to go!
I have some of the chalk powder and was advised to add it to water so it was quite thick (I used 3 parts chalk, 1 part water) then applied it to his socks, left to dry and alot of it fell out but I brushed some of the power out, and it lasted several days
So if its already in a paste, maybe just apply it directly?
(Halfway through the post I realised I was talking about powder, not paste, sorry )
Its so good, my horse looked like he had bandages on from a distance!
Well, my plan actually is to make the powder into paste He's a hairy, lots of feather. Normally rub in the powder but wondering if paste might be better...
When I showed my coblet I just used the powder as it was and it worked brilliantly. The judge said that she could not find fault at all so I hope that helps.
if tried useing powder without adding water before and it didnt work too well (might just have been me) but i find i thickish paste and then bandage legs (use gamgee under the bandage) works best.
My horse is clipped on her legs and has 4 white socks and most of the time i find it easiest to just wash any new stains in the morning. But i can see from your signature that with your lovely hairy that wouldnt be very convenient
The one we are currently using works best if you damp the legs lightly (not dripping) with water, then using a slightly damp sponge to put the powder on,
If this is for your traditional I would not not use it as on long feather as it stops the hair floating freely when they move and makes the hair look coarse when you want the hair to look silky. If you do use it, make the chalk/water mix is very thin and paint it into the hair the day before. Leave to dry and make sure you really brush out.
You are better using talc or a little dry chalk on the day. I use talc and find this is the best given the choice.
Or, if you must use something on the hair, use a little supreme leg whitener again made very thin, but only on the tips of the hair. Finally if you have a traditional and a black tail, the whitener goes all over the tail, leaving it a dirty grey colour, so do be careful. Talc is ok, but anything else no matter how much I have brushed out has gone on Stinky's tail, hence why I avoid them.
Far better to have free flowing hair that is not pure white, than clogged up hair.
