Bog, from my experience requires a rough surface (80-120 grit) foothold and=
a chemically sterile (i.e No wax, grease etc) surface to perform a good bo= nd, but even then you have to consider your hardener ratios, humidity, temp=
, and material permeability, flexibility to gain better performance. even t= hen bog under ideal conditions does not like temp variations, heat, dissimi= lar materials (i.e metal and plastic in the same area to be bogged), substr= ate surface expansion (ie. sheet metal on a hot day) and especially, shock = and vibration. An alternative maybe fiberglass, resin, carbon fibre or 2pac=
k polyurethane resins from easy cast which is like castable pvc in a way. i=
t files, joins, flexes, and stands up to more abuse than bog. But with stee=
l, Alu etc weld smoothing bog is still king due to these parts made by comm=
on ferrous and non ferrous materials usually are rigid non flex stable comp= onents i.e vehicle non structural sheet metal if the prep is done right tha=
t is. I've used "easy cast" (2pack polyurethane resins) before on similar p=
vc projects and found it vastly outperforms, compared to bog. You can by th= ese easy cast kits from Riot art supply for approx $45 Aud or online i gues=
s for less, these kits come in various sizes from 250mL to 1L and comprise =
of instructions of use and part A bottle (resin) and Part B bottle (hardene= r/catalyst/ accelerator). You could even buy silicone mold kits and "pour" = one piece parts from scratch using easy cast a silicone mold and a clay die=
(original relief cast for the silicone mold). Hope this helps.
