Re: who's applying photoresist film ?

Hi, I have just ordered some dry film solder mask from the following
link. I think I remember talking to a rep who said this stuff is
pretty good. I shall hopefully try it over the next few weeks.

I nearly bought some of this photoimageable solder mask because they
sell it in several colours but the process does seem a quite a hassle.
I think I shall get round to trying it at some point but the green
film seems the most practical for now.
