## Questions & Answers

**Q: Can this be used on a aluminum boat?**
A: This would probably work for a general washing, but a better cleaner for aluminum would be the M19532 Pontoon and aluminum boat cleaner.  thank you  Eric

**Q: Is this safe to use on Awlgrip paint?**
A: yes

**Q: Can this be used on an airstream with alcoa coating?**
A: Yes.

**Q: Is this product Duratain compatible?**
A: Its PH neutral and very gentle.  I use it on coated surfaces all the time. Boats, Cars, RVS.  Its highly concentrated too.  Call Mequires or Duratain if you want to be
absolutely sure.  I was surprised to see the Duratain suggest dish soap like dawn to wash on the surface.  That is 
far more harsh that M5401!  Good luck
