## Questions & Answers

**Q: Can these be used to smooth wooden house siding prior to finish coat painting or are they too agressive for that ?**
A: I would think an orbital sander might be more applicable for that kind of sanding.  Note!:  inform yourself on lead based paint requirements!   If home built prior to 1978 (I think), the original paint might contain lead, and if so, federal agencies can impose stiff fines, etc for improperly disturbing.   If the lead becomes airborne (from sanding or other processes, it can be breathed in and is toxic to humans, especially kids.But getting back to your question, I would think this flapper sander too aggressive - no matter how sure or gentle a hand you have on the grinder, it would no doubt put wavy marks on the siding.   I use these discs to grind weld beads and they are awesome for that purpose - they remove metal really fast and are also great for rounding sharp edges or cleaning up the weld area prior to welding to insure a clean weld.
