Hi guy's going to ask a taboo question here.

What is the realistic use of bog people use, im talking everyday people here who are just having a crack.

I know everyone says 3mm and thats the maximum, but realastically how much do people use.
Im talking proper quality stuff applied in thin layers to a very rough surface.

Ive seen at least 20mm applied to cars that have lasted for years, and seen tiny skims that fall off.

Ive got a tin of filler here designed to fill dents upto 6mm deep, evercoat and thats off the datasheet.

I know that no one wants to admit to using the stuff but I really wnat to know first hand from normal people so I stop fretting that im shit.

i have seen many e series rear wheel arches full of bog 10-15 mm deep.
i had a mint looking xc ute it was sprayed in a honda blue looked great,then i found the rear quarter was a inch deep with bog. lucky i bought it to rip out the clevo not the shell.
if ya want to feel happy with your work beat it till its smooth and only use a high fill primer or spray putty.

Is be more concerned about what you are applying the bog to than the actual thickness. As long as there won't be any give or flex in the normal use of that panel then its all good.

Even with very rough panel work you would have to try hard to have bog anywhere near 10mm in height

6mm is the most you want to go to...

bog doesn't flex with metal, so it can crack out..etc...

I've seen whole panels built from it.

Poly fillers flex beautifully. We even have filler specific for bumper bar use that flexes even further.

Generally, more than 3-6mm is a no no. But once you do a layer, sand it back and then another layer and so on and so forth, sky is the limit lol.

You want the metal as close as possible to it's original form before filler, but be careful not to hammer/beat so far as to stretch the metal, as not having an oxy or electric shrink on hand will make things difficult.

thats good to know!
does it resist lifting more because of the flex properties?

As long as the surface is correct. For bumper bars/plastics, the surface should be finished in 180 grit at the least, 240 preferable before applying fillers.

Metal, finish the surface in 80-120 to prevent shrinkage but still giving a well keyed surface before applying filler.

If applying filler over filler, 120 or better is best to finish before applying the next layer. Be sure the surface is thoroughly blown down too.

Ultimately, plastic and metal should be blown down and cleaned with wax/grease remover before applying filler.

Bar filler is still shit...i don't like using it...

Bog isn't a shunned thing either, everyone uses it...all those show cars...


Edit, thats an massive contradiction haha

Oh hang on a sec, never claimed to know what I was on about lol.

Hey Nik, different brands of filler can have different results. Even some very well known fillers are absolute pox. We use 5 different brands, depends on what's required of the filler.
