    Hi. The part below is off the bull bar assembly off my Mitubishi Delica.

    Majority of it is behind a platic cover.

    I was going to paint it but then had 2nd thoughts as getting it clean will be a pain.

    Trying to keep costs down, what would be my best option?

    Persevere and paint, galvanize or powder coat?

    I have only had large frames galvanized and wondered if the process would damage it?

    Galvanising isn't big money, providing you're not dealing with one of the wedge group.

    Any idea of cost. I know galvanisers charge by weight but do they have a min order charge.
    Only every had a few ton at a time galvanized.

    Powder coating [cost aside] would be my choice in your circumstances. Shouldn't be prohibitively expensive though?

    Powder coating will crack in no time and let water in and rust

    Glav or wet spray it

    Like I say, wedge charges a car parts premium, and then (in my, and other people's experience) do a abysmal job anyway.

    If your local plant is non wedge, I would imagine less than the cost of any other option, but, really I can't say - just call your local plant and say "I've got about X kg of steel (don't mention cars) to be dipped, what do you charge..."

    Ps

    For dipping rust is fine, but you will want all the paint etc.off it.

    I've got a lump of somthing that I'm going to dip at some point. It's thick steel. I don't have a blaster, so I sanded it, it's sat outside with a good layer of brown surface rust, and that has shown the spots of paint I've missed, and need to go over again with the sander.

    Another vote for powder coating.

    Your local place may be able to add it to an order.
    Or make it into a "Many parts "order.
    Specially if you use a common colour

    Powder coat is GARBAGE. Water gets behind it. Rusts then coating peels off. Only suitable for dry interior use.

    We did a friends Fontarna Front Light bar, his after market roof light bar, over 10 years ago.

    Still going strong. But then we did seal any holes and greased to bolts. To date not watewr has got in it.

    Sadly the grab handles in the rear got scratched, they have rusted.

    An alternative to powder coating is Cerakote, it is ceramic based and is reported to be much better than alternatives; long lasting, good wear resistance, handles heat, etc.

    galv is best.....needs to be local to keep costs down but often they will pick up ur stuff but u'll need to drop it off at a desegnated place.....
    cost is really peanuts...AS LONG as it's clean, grease and paint free and has the necc holes predrilled for air to escape.......
    have seen something like a £5 charge per hole for those who forgot....I like a 6mm hole as a min size....
    normally priced as......the weight of ur item, hollow or solid pluss there %centage....
    the last item I had galvanised was done in Southampton, a fire escape staircase (single storey) and landing frame plus the hand rails....so, some solid and some hollow......
    dropped it off Monday morn, collected on the way to the ferry Thursday afternoon....total cost less than £500 squids.....inc tax....
    great people n helped me load the van....
    in France the same item was €2000 plus tax......
    nuff said I think......

    sorry but thats cobblers, bad powdercoat allows that to happen not good powdercoating.
    its all about the prep as to why this happens
    ive had load of component parts powdercoated on my car without issue

    I’d agree. Although I only powdercoat small items, the only failure so far (touch wood) was due to me handling the part with bare hands after cleaning, and prior to powdercoating.

    What's the wedge group? What's the price difference?

    Its for a Delica :o, if it was coated in salt water it would probably outlast the car :) Only joking, I would have thought a decent coat of 2k would suffice. As James said, its all in the prep.
