what is alodined ??

[steve]

the gold colored coating that Merc uses on all the blocks etc. Not anodizing, alodining in case there is confusion. It helps paint adhere better and protects against corrosion.

Zinc chromate etching primer is the only primer I know that will stay on aluminum.It is that lovely military green color.

Alodining is not primer. Primer goes on over top, then paint. Google it.

well it sounds like Wayne was right. If you do it wrong it will just peel !!! IT HAS TO BE DONE RIGHT WITH THE RIGHT PRODUCTS !! just like ultrafast stated. There is a right way, and a wrong way.

I've powdercoated lots of stuff for immersion service in saltwater, work for the navy. If done correctly the stuff is bullet proof. But, if its going to see high temps make sure you got the right stuff. Paint can be chipped just as easy as powder. If it peels off like wall paper then you should go get a refund from the guy who powdered it. If the powder chips repair it the same way you would a paint chip. Lightly scuff (feather) the prime and paint it. It ain't gonna hurt the powder with a little spot of paint and yes paint will stick to it. The key is prepperation just like paint. Ya gotta use the correct media to blast the peices with. Aluminum oxide don't leave a residue (surface contamination) then ya take some xylene and spray it on with a squirt bottle and blow it off with air nozzle till its dry. Then you end up with the cleanest peice of metal and just begg'in for some powder. You can heat it and shoot it hot for a thicker coat or let the electricity do the work and shoot it cold then heat it. But, if not done right it can end up being really brittle. good luck
