if you are going to have it flocked send it to a proper company, no battery powered machine is going to creat the static charge that flock needs as well as the proper equiptment to spray it and clues and prep
i used autoflock motorsport on my old cossie, i had everything done from dash to door cards, ad some carbon and it looked great
there is an evo also that has his dash retrimmed in alcantara and red stiching and it does look pretty amazing, but to do it right you are looking at over 400 id say, unless its just the top piece of the dash you want doing, but even then dont forget about the passenger airbag, so this needs to be taken into account that it needs to be able to split apart just incase, this is why just using alcanata and doing it yourself isnt really a good option unless you remove the airbag
and get proper stuff as a lot sold isnt uv stable so will soon fade and turn a nasty green or purple
