Sounds ok, my brother-in-law, my paint guy, refers to the MS Prisim urethane as bulldozer blade paint. As I said before the real trick here is in the prep, followed by a real tough finish that is ment to take all sorts of abuse. A local shop uses the Prisim to do road plows and salt boxes, they see it hold up for several years with no problems.

Merc paint is no better than any cheap chit in a rattle can, total waste of time and effort. Been there, done that. A quickie with Rustoleum and a cheap brush will give you far better results. Think about it, if Merc paint held up well, would you need to repaint?

Does merc. have a paint code# for black that is used on the outdrives ?

Ive researched paints just a little and theres a great paint few people know about and its 10x tougher than Imron or Awlgrip and cheap at roughly 50 a gallon its BLP Mothane paint. Mostly used in the yacht/ sail world. Call and talk to the paint engineer and you will be impressed hes tested these 3 and others side by side and outperforms hands down
