For what it's worth I used Pledge for years before Honda Polish or Protect All came out. I used it for "touch ups and NOT as a "total bike" cleaner. It works great,in fact when Protect All first came out,it was accused of being re-labeled Pledge. I actually called the OWNER of the company (it was tiny,tiny then) and he admitted that it was based on Pledge's formula but with some additives including carnuba wax. Apparently,the oils/waxes that are in the original Pledge don't adhere to plastic/paint. Also,Pledge washes off with water and doesn't offer ANY paint protection what-so-ever. Remember,I'm old and Pledge was originally designed for stained wood furniture. The "lacquered thing" didn't start until later... Also,if you are going to use Pledge,you should probably get the original formula or you may as well use 409 or Fantastic on your bike,which is what the "Multi-surface" Pledge basically is.
Oh and Protect-All FTW!
