you can buy metal glo polish at military or police accessories shops... there are plenty at santolan-edsa near camp aguinaldo and camp crame... which regards to the 3 polish, basically all the same in terms of finish... if your hub is metallic, then it will restore that finish... but if it is dull then expect a dull finish no matter how hard you wipe and scrub it... it is better to apply the polish at a cloth before applying it at the surface for an even application...
with regards to armor all, you can use it in your dashboard, leather seats, plastic flairings etc. i am also using it with metals and so far the effect is also good...
hope this helps ts...
