How easy is a product to use when you actually get it home?
The only way to know for sure is to review the product instructions before making a purchasing decision.
If you do not exercise the proper due diligence you may wind up sorting thru a box of brushes, miscellaneous sprays and other useless paraphernalia.
Don’t be afraid to ask questions and walk away if you encounter any type of resistance.
Insist on reviewing the product instructions before completing the purchase.
