landroversforever Posted August 10, 2014 Share Posted August 10, 2014 Had another thought this afternoon regarding coating my new galvanised chassis. I like the look of fresh galv, but don't like the dull grey it goes after a while. That along with wanting to protect it, it will get coated in something. So, has anyone had a galvanised chassis powdercoated? I cannot decide in my head if it is a good or bad idea, so all thoughts on the matter are welcome. I think I'm still leaning towards painting...

western Posted August 10, 2014 Share Posted August 10, 2014 Decided to paint mine as we discussed at our last meeting, powder coat can chip & split so road dirt & moisture can get between it & the galv, I had the option to buy a fully powder coated galv chassis from marsland, it was a cancelled order, but after advise from others on here [see my chassis change thread] I bought a new plain galv chassis instead. the rest is now history in my thread.

Team Idris Posted August 11, 2014 Share Posted August 11, 2014 Marmo Coatings do many galvanised posts for a customer in powdercoat. It's all down to the key. I don't know how you get that key to be as good as it can be? But you know how to with paint, so I guess paint is the one to use, as it is a technology you understand? e.g. (I'm not geared up for tig, but my ideal duct was ally, so I used glass fibre because it matches my facility/ability) Quote Link to comment Share on other sites More sharing options...

garymorris Posted August 11, 2014 Share Posted August 11, 2014 Usually they will sweepblast something that's been galvanised to help the powder coating key in. They have to do something called degassing which stops the powder coating going funny /porous. If you don't want to leave the Galv finish then t wash/ mordant solution and paint it like Ralph did Quote Link to comment Share on other sites More sharing options...
landroversforever Posted August 12, 2014 Author Share Posted August 12, 2014 The galvacoat isn't designed as a durable finish, its more for aesthetics. Looks like paint is the way to go still, mainly that I can't repair a powdercoat finish whereas I can easily touch-up a painted finish.

Lewis Posted August 12, 2014 Share Posted August 12, 2014 I remembered this thread yesterday whilst at work inspection some parts. I was scraping the powdercoat off a galvanised item with only my thumb nail, hardly a durable finish Quote Link to comment Share on other sites More sharing options...
Tanuki Posted August 12, 2014 Share Posted August 12, 2014 Getting paint/powdercoat or any other coating to stick well to a galvanised surface is a hell of a job if you're confined to using commercial-over-the-shelf products(same as for aluminium and stainless-steel!). Surface-abrasion followed by a suitable etch-primer is the way to go. Alternatively - if surface appearance is not *that* important, a slathering with old-style bituminous paint tends to work well: I'm aware of some galvanised steel pipes whose welded joints were treated this way and they survived quite happily being buried under a beach in Dorset since 1959.

Diablo Posted August 13, 2014 Share Posted August 13, 2014 Vinylast - from a company called Rourkes Goes straight onto galv, no real prep needed (the usual degrease and a very light keying). Mine's been on probably three years now and, other than the filth, looks almost like I put it on yesterday. Fantastic stuff. Welcome to come and look my Landy if you want to.
