There is no problem, aluminum is very conductive.
Bonding = grounding or grounding straps.
However there is a recommended method for attaching bond straps or ground straps to aluminum structure.
In the USA the FAA has "Advisory Circulars" to give guidance and good or "BEST PRACTICE".
Electrical bonding is: AC 43 13-1B, Chapter 11, Electrical.
Attaching to aluminum structure may cause dissimilar metal corrosion. Typically "passivated" washers, screws, bolts and nuts are used to secure a ground strap to the airframe. This is BEST practice and reduces chance of corrosion.
Some builders run a separate ground wires to each component, for example lights in the wing tips or tail. Some builders ground to the airframe locally. Both methods work fine. The FAA accepts both. Again the bolt, nut and washer touching the aluminum structures should be "passivated" hardware. Passivated is neutral and resist corrosion on the aluminum or hardware.
