Brought some dirt cheap wood from Lowe's, not even tagged as to what
it was, for a garage project.Exiting pieces are ash, this has same
type of grain but softer. Used sanding prep liquid, let it sit, wiped
it off, applied stain, and it came out looking extremely blotchy. This
has never happended before.

Dont' want to buy a piece just for this project. If I use shellac to
seal it, and appliy Minwas stainer and sealer (not jell) on top, will
it still have blotches?
