Greetings,

I have a question concerning the 'wet method' of making circuit boards. Since I am new to making circuit boards I did a search a while ago and found kepro circuit systems and purchased all the items to make circuit boards using the dry film method. After it was all said and done and everything was shipped I had quite a bit of money invested. Since I have been following this group I have heard people using 'lye' as a developer. My question is this: Are there any common chemical substitutions which could be used replace any of the development stuff kepro sells? Example: developer=lye, stripper=bleach??, tinplating = ?, acid= ? etc.

Thanks Much!
