yes,Ive got baking soda and kero ones here that were done 30ish years ago and they are still good...just dont get them wet.
the leadleiters kits are really good and there are a few other kits around that work well too.its not rocket science to get a really good end result,just take your time and dont rush it...the better you brick it afterwards the better it will come out....pumice stone is great.
the local library is your friend,there are many books written 30-40 years ago if not longer that are full of knowledge but people no longer read books ,preferring to ask uncle google.
