They did offer onsite training. However, the quote I got didn't give me the impression that they wanted to do it.

Hi Pavel here in Poland interflux sells a product C8 who can remowe the solder mask, no disolve. It is a high alcalin product with other stuff, you can ask to vsd@interflux.pl jean vadim
