langka or front line ready stone chip system ?
 

We have a 07 night blue pearl a6 with stone chips here and there.
The largest being the size of your little finger nail on the pass door.
Any of you guys ever used the systems I listed?
I like the flr for the smaller hood chips but the langka for the bigger stuff..
I have not used either but need to fill the stone chips before I polish, seal and wax this fine auto..
Thanks in advance...
