Finishing PE

12-07-2015, 12:24 PM
One thing I don't see discussed here much is how to finish PE parts. I struggle a lot with this. I've tried using keys, steelwool, self-etching primer and nothing seems to work. I get the final finish on the part and if I even look at it sideways a big chip falls off and exposes the raw alum or SS or whatever material it happens to be.

So I thought I'd ask and see what process you guys use to finish PE parts.

Have at it!

Can you give some details as to the kinds of pe parts you've had trouble with? There are different techniques I use for different situations. As you've noticed, pe can be terrificly difficult to paint (or keep painted)- it suffers from being both metal and flexible. But some techniques may work better in certain situations than others.

What you need is some Etching Primer to bite into the metal. Try this one
