Polyester Resin Wall Plug

I'd use the resin to glue some chunky wooden dowels in, then woodscrews into those.

If you mean "car body filler", you can almost drill and tap a machine screw thread into it - a woodscrew is likely to have difficulties.

You can't fix anything into resin after it's cured. The usual method is to embed lengths of threaded rod, and then use a nut to fix after it's set hard. If that won't work for your purpose, then resin might not be right solution.

You could glue wallplugs or wood in and screw into those with wood or pb screws. Gluing threaded rod in would get you a lot more strength. But why resin?

You certainly CAN screw into cured resin and body filler - but as it has little or no 'give', you've got to get the diameter of hole you drill just right. It's usually easier to embed a plastic Rawlplug - or after the resin's cured, drill a hole and fit a Rawlplug.

Just treat the cured filler as masonry. Toolstation's Profil is the cheapest if you only need a small amount. A bit gloopy for my liking but works well

rubbish. If you drill a pilot, a self tapper or indeed a woodscrew has every chance of cutting a good thread into it.

Its similar to hard oak in that respect

The small tube is handy as it comes with a doodah that lets you use it in a normal frame gun, rather than needing a dedicated gun, also be aware the resin does come with one nozzle.

You have to strike a balance between bursting the filler apart with the wedge action of the screw (old woodscrews in particular) versus the likelyhood of the screw not cutting a good thread.

I was thinking more of this. Use it for 101 other things too

Absolute total wombat turds

its got quite a lot of give depending on how filled it is and with what.

so just like wood,metal,plastic or anything else you put a screw in.

Equivalent to a piece of oak I'm guessing 1cm diameter in a much softer substrate.

Good luck with that...

Never tried that.
