So I decided to bottom paint my outdrive on my 270. I was originally going to use Hydrocot Eco because it contained no copper and was the best Hydrocot product for outdrive. However I took the suggestion of my mechanic and Wildboating to use Interlux 33 in the spray can. Today I prepped the drive my a light sanding and used the Primo Interlux primer. It literally took 2 minutes using the spray can. Next week I post a picture after I spray on the Interlux 33. Believe me using the spray can if the way to go!!
