Next the paint was removed and final panel beating was done.This big dent proved to ba a problem.The metal had fatigued to a point where it would pop in and out.To fix it we used an oxy to heat a few spots and cool rapidly with water.This has the effect of putting the strength back into the metal so it doesn't pop.Unfortunately this left a few high spots that couldn't be removed.Each time we knocked them down another spot would come up.In the end we beat the whole ares down a little and used bog to fill it.Not as good as getting it flat first but we only needed a couple of mills of bog so not too bad

The first layer of bog is a rough fill.We put heaps on and as it starts to go off sand most of it off leaving some low spots but a fairly flat panel.Always use a long speed file to get the panel as flat as possible.The longer the sanding tool the better the chances of getting it flat.

Once the base layer is done we just used a thin smear to fill any low points.

With the panel looking pretty flat we hit it with some highfill 2 pac primer.

I will leave it for a couple of days to settle then start the final sanding in preperation for painting.
Just a discalaimer.I am not a panel beater and while this technique works for me I have no idea if it is correct..
