I just tried putting this thread up,but it didnt seem to go through,so her goes again.
We put the Proparmor on our boat last season after it was recomended to me by a good buddy.
I purchased it at West Marine.I didnt use it all up on the boat even though the sales guy told me to apply it to the sea strainers,so we can use up whats left next time.
Ive been under the boat and taken a look and Im very happy with the result,I wouldnt use Propspeed again.
Proparmor is a better product and it costs less.
Hope this helps
