Painting drive with delfleet

[vroom ZOOM]

Hello, I want to try another paint/process for one of my transom plates.

I dropped it off to have it laser cleaned so its basically going to be perfectly clean from paint corrosion and grease. I want to etch it with muriatic acid, and then apply alodine. For paint, has anyone tried painting drives with delfleet essential? This boat will be wet slipped for several months in fresh water.

For another drive I tried painting with self etching green primer, then followed with 2k primer, and finished with SW sunfire pro single stage acrylic urethane. The paint is still all on the drive after a month in the water, but it did start forming a bunch of small bubbles. Don't know if that is due to me rushing the paint process and not letting the paint cure fully before dunking the boat in the water, or if the paint is not up to snuff.

I've never heard of alodine, and had to google it. Reading this article

it doesn't really seem great for your application. Ppg makes good quality paint, although I've only sprayed it I think twice.

As to the part about your last paint job, not letting it cure fully would definitely not have helped. Acid etch has been replaced by direct to metal primer. The acid etch can also bleed through if you don't let it fully cure before primering. I didn't really get to spray it before we started getting the DTM primer. As far as I know, acrylic and urethane are two different kinds of paint, with urethane being far better.

So the best advice I can give, based on my experience, would be to sand it all with 220, spray with dtm primer, scuff with a scotch brite when cured, spray with 2k urethane primer (the dtm we use isn't high build), sand with 320 when cured, and finally spray with the ppg single stage you want.

What color do you intend to spray it?
