New Rubbing Strake

[Thames 4 Blood]

Considering fitting a teak rubbing strake to Moonshines pretty flanks. Partly a cosmetic exercise but a bit of extra protection should anything get past the fenders.... Either 25mm sq or possible 32mm sq.
Anyhow, how best to fit teak rubbing strake to FG hull???
I reckon from experience that a good sealant ( Sikaflex ) will do all the bonding that is required? So I am hoping to use minimal number of self tappers primarily to hold in place while sealant sets. As in 1 self tapper per meter or so...
Any critique of this scheme would be very welcome!
