imran bhai yes its good idea u also arrange similer gtg in karachi at same time , date and as usman bhai said earlier can synchronize both meetings through skype etc
you and omar both are in karachi why not u plan ur cars detailing togather, its realy fun and learning from each others.
presoak is megic but i dont think its need in every wash, i think once a month enough to keep ur engine bay clean, may be first time u need some extra time however in followup washes will take just couple of minuts to spray and wash.
omar you are most welcom here in lahore and lahori khane
by the way "dc" logo on front grill seems most attractive
