[lsw11 New User Find all posts View Profile Close lsw11]

Hello,
i plan on making a piece (intake) i want to send it out to get coated. Actually made one this weekend but didn't like the slots i cut in it. What kind of prep work should i do to it, it's made out of mild steel ? I plan on using a flap disc to sand the outside whcih makes it smooth and shiny, but do i need to this for the inside since that will be coated too?
Thanks, Luke

Re: prep work?

normally the powdercoater will want to blast the part themselfs to ensure proper bond of the powder so it may not be worth the extra time on your part.

Re: prep work?

i have another question. with coating mild steel, should it all be sanded so it is shiny on the outside? does it make a difference if it isnt sanded the whole way down and is just bare metal?

If the coater is going to blast the part, it will not matter.
