I think its a vcd, and aren't there printed instructions on the back anyway?

the block, its damn near useless and is supposed to be used so you can form part shapes (heat it in boiling water for 5 minutes first) by pressing it onto the object to clone.
the little bottle, thats to be used with the "needle" to meter the fluid while applying it to the join
the pippette is used to take fluid from the glass permenant storage jar to the plastic bottle, put any remaining fluid back in the glass jar when you are done else it'll evaporate.

the one thing they *REALLY* need in there is something to move the powder from the containers to the repair. After much experimentation i found that the best way to do this is to get a straw and cut the thing so theres a rather sharp angle cut across the straw and then square the point off so its 2-2.5mm across. I've used this setup for quite a while and the straw has earned itself a place in the plastex toolkit as a permenant entity.

I tried doing the "mix externally" idea, but i could never ever get it to work for me.

If it hurts, you aren't doing it right.

i used the block successfully on fairings like the zzr250 nosecone where one of the screw holes had vanished , make a mould of the other side , tape it to the broken side then fill with powder and liquid

iirc they advise using glass on stress points

dont do this stuff when the weather is too hot , and the powder goes off after a period of time and wont glue properly anymore so dont buy oo much of it and keep for later

google abs plastic and acetone , you can make your own glue which works in a similar way , anyone wanting to try this out pm me as i get plenty of white abs plastic

I repaired all of the issues on my fairings with a soldering iron and some cable ties.

Use the cable ties as your welding rods and use the soldering iron to melt them.

Pack the plastic into the cracks or holes then file, sand, more sanding and more sanding before priming and painting.

It takes a while and a bit of work but you cant tell where the repairs are any more
