Great prices

Good to go

I have not installed the prop yet. But I did get it and it was not damaged.

Will buy from here again.

boatplicity provided the prop paint product that I needed and wanted at a very good price. Why pay the overpriced WM item? Ordering was easy, the free shipping option was a great feature and helped me go with boatplicity for my order. Shipping time was good. Didn't need it immediately and I loved the opportunity to use their offer.

Shipping was unbelievably fast. Thanks very much
