Ok finally got my product in post ... So out the garage and sorted 
First applied product ( acid free ) then left to stand then agitated with a micro fibre alloy wheel brush ( non metal perfect size for vee spokes) got right inside the entire wheel . Left to stand again then power washed of . Considering the wheels already looked good the amount of stuff that came of was surprising . Once dry finished with some dodo juice acrylic spritz sealant
Some results above
