Here is the weed spray car I scratch built. I used the underframe from a 40 foot box car and an VO1000 cab, The rest I used plastic pieces and steel wire for the spray hoses.

Here's a way to make a model one: https://www.trains.com/mrr/how-to/build-model-railroad/build-an-ho-scale-weed-sprayer-for-fun/
I never have, but they seem to be something others are very interested in.
Weed trains in brass command very high prices.

Living the dream.
There is an article on kitbashing a weed spraying outfit from a maintainence of way car in the October MR. It provides a lot of interesting info.

"One difference between pessimists and optimists is that while pessimists are more often right, optimists have far more fun."
I am currently building a weed spray train. I have the scratch built spray car and one of the two tank cars completed. Has any other forum member built a weed spray train?
