How does one add my mod blocks to be added as a facade? I was told to use this but it does not work

"FMLInterModComms.sendMessage("BuildCraft|Transport", "add-facade", ModBlocks.BlockTaintedGlass.blockID + "@" + Strings.BLOCKTAINTED_GLASS);"

I'm not sure if this is right place to ask some help but if anyone could help I would be most appreciated!

What I use:

FMLInterModComms.sendMessage("BuildCraft|Transport", "add-facade", String.format("%d@%d", block.blockID, meta));

meta being the block metadata ofc

Oooh.. so one could .. facade all the blocks?
