freeing condenser coils

[baja1]

I have two chest freezers (one a fridge conversion) that I use off grid in baja.I removed the outer metal skin,freed the coils,added 3 inches of foam then covered with frp and reattached the coil on the outside. I also relayed a 12vdc fan blowing on the compressor.
my questions: do these freed coils make a more efficient appliance or does the metal sheeting disperse the heat better? also does a fan blowing on the compressor cool it at all? and would a small fan inside the box add anything?
these units are being used in 110 degree heat.
thanks guys im gonna try to attach a pix.
nope cant figure that out

okay heres the chest freezer

it's looks beautiful.
1,sheet metal is better than frp.
2,the fan blow on compressor is not necessary, if 110 degree is inside designing condition.
3,if evaporator is a coil reattached on inside skin, the fan is waste.
