Lower unit Painting

I have removed all the paint and will use an etching wash before painting but I'm getting conflicting methods of painting.
I'm going to use Interprotect 2 part epoxy and they say I can just put that on right after sanding.
But their directions also showed using their zinc chromate paint first, which they no longer manufacturer.
Should I spray an etching primer first, like Rustoleum Etching Primer or Moeller Zinc Phosphate then epoxy? Moeller doesn't carry the zinc chromate any more.

Check napa auto parts I think they may carry it

DON"T PAINT IT!!! If the LU is for a "go fast" send it to East Coast Powdercoating (Bud Conner...member S&F) and have him apply the hi-speed SS coating that should be good for at least 1 -2 MPH. Bud is a perfectionest and you will be real glad you did! I don't have any pics but mine is a piece of art! Gary

Totally agree. And it will stand up far better over time.

I'm getting ready to strip my clamp and can. I have a hand blaster, but unsure of what media to use to blast it.

Glass bead (fine)

Thanks, I'll give it a try.

I see you say glass bead, but at what sort of pressure ?
I have a big tank I made myself (50 gallon drum ) and can get big stuff in there. I will be stripping down a lower unit too.

I have very fine glass beads , I didn't get crushed glass as heard thats not so good. hardly any price difference too.
being in a tank I get to keep the beads to re-use.

I built a cabinet out of a trash can also! I use just enough pressure to strip the paint and leave the aluminum a consistant color. Start at 50-60 lb with a big nozzel.

sounds good.
I will give that a go soon, need it to stop raining so I can get the electric out to the garage.
I can fit a lower unit in here now as have a hole in the door to poke the drive shaft through.
to stop dust getting out I put a bit of inner tube from a bike on the door where shaft goes through a hole..
I have found some props are hard to blast, the Teflon coated are the worse.

I like that ...I just bend over the trash can with my arms on each side of a peice of plexiglass to look thru.

anyone have a number for east coast powdercoating
