Hybrid_From_Hell Posted September 28, 2007 Share Posted September 28, 2007 Hmmmmm I am very shortly to have some new wheel rims delivered, they will be bare steel. When I 1st got my Mach 5s, I had them blasted and stove enamelled, on the tyre machine as they put my tyres on I saw the stove enamel start chipping off, where the rattle gun does the wheel nut up its chipped awy and whacks and smacks off road sees further chips, so I think in hindsight stove enamelling them was ok, but not that good. Powder coating ?, unsure about that now, Galvanizing is out as is Zinc Passivate etc. I have thought maybe low tech, spray with a light coat of paint, then I can just respray when needed, the thinner the paint the less likely to chip peel off ? So, if you had a set of bare steel rims what would you paint / cover them with and why ? Nige Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted September 28, 2007 Share Posted September 28, 2007 Humbrol Enamel in the little tins. I'd just etch prime and a couple of coats in the colour of your choice. Easy to do, quite rugged and easy to touch up if ness. Mo Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted September 28, 2007 Share Posted September 28, 2007 I usually hate the stuff but I've seen a set of Mach5's done with gunmetal grey hammerite and they looked good. Nothing is impervious to rocks, so it's whatever you're happy touching up really. Why is galv/ZP off the menu? Quote Link to comment Share on other sites More sharing options...
s2hotdog Posted September 29, 2007 Share Posted September 29, 2007 Nige Flame Zinc Spray then paint and keep repainting the unavoidable damage Or Galvanise and leave Depending on what finish you want Just my thoughts Steve Quote Link to comment Share on other sites More sharing options...
MogLite Posted September 29, 2007 Share Posted September 29, 2007 What is the finish on things like Machine Mart engine cranes ? Thats pretty tough. If I was doing wheels properly I'd do - zinc spray, etch primer, new Hammerite sprayable The latest hammerite brushes on in two coats really nicely, and isn't too shiny. Just repaint/touch in as necessary Andy Quote Link to comment Share on other sites More sharing options...
white90 Posted September 29, 2007 Share Posted September 29, 2007 I just used some 1 pack paint designed for excavators seems very tough so far. Quote Link to comment Share on other sites More sharing options...
English Gent Posted September 29, 2007 Share Posted September 29, 2007 My bare Mach5's were painted with normal primer and white enamel coach paint. It was easy to do by hand for my Dad as he used to be a coach painter. After lots of use and abuse the white paint started to chip and peel as all surface applied paint will do. This summer I took them off in pairs and rubbed them down with emery paper, scotchbrite pads, wire wheels and brushes, and then repainted them with two coats of black smootrite brushable paint. I'm no painter, but the finish achieved is pretty good even if I say so my self. The problem with doing a proper job, is having the time to leave the vehicle on stands, or getting hold of some spare wheels whilst doing the aforementioned 'proper job'. Personally I would always look at rust proofing in degree's of suitability. The chassis is the one part you don't want to change, so hot dipped galvanisation is the only way to go. The likelyhood of distortion is minimised due to proper design of vent holes when fabricated. Assuming you have an already used chassis, then pressure cleaning the insides and then flooding with waxoyl are going to be about the best you'll achieve as the zinc won't take over any accumulated grime. For any other types of steel parts, hot dipped can produce thermal distortion when combined with excess pressure build up, this was why my bulkhead was not recommended for hot dipping. In the end, I found a 'paint' called 'Zinga' which is 95% pure zinc, designed for in the field applications and suitable for repairing previously hot dipped galvanised metals. The problem with Zinga is that for maximum durability the parts should be sand blasted first... I needed a BIG cabinet to get my bulkhead back to bare metal. Your wheels could be zinc passivated with POR-15 (I think that's the stuff) as I successfully did my axles casings in that. You just spray it on and keep it wet for 30 mins or so. The problem with paints and indeed plastic powder coating, is that the surface adhesion is always the limiting factor. The good thing about Hammerite smooth is that a big tin goes a long way, and it's easy enough to keep touching up, rubbing down or simply overpainting.

BogMonster Posted September 29, 2007 Share Posted September 29, 2007 I just used ordinary aerosol primer and metallic silver on the last set of wheels I did, and finished off with a coat of proper "wheel lacquer" to give it a bit of toughness - seemed to last fairly well. I think if you belt it on a rock it will damage the finish whatever... with the possible exception of galvanising. Quote Link to comment Share on other sites More sharing options...
bishbosh Posted September 29, 2007 Share Posted September 29, 2007 Bare steel rims Nige? I'd put some tyres on for starters!!! My hat? Why thank you!! Quote Link to comment Share on other sites More sharing options...

So, if you had a set of bare steel rims what would you paint / cover them with and why ? Nige Nige, I have just bought 5 x mach 5 rims and had them shot blasted, cleaned and powder coated. The tyre fitter used a silicon pad under the tyre / rim rotary fixer thingy with no damage, this set have the latest mach 5's rolled edges. My other set were straight edge and chipped on the first tyre fitting After last weekend at the Belgium National (yes it was run but with only 3 Brit cars) a couple of rims have a few chips, but we were upto our necks in Belgium mud and crud I think that whatever the finish taking the rim off-road will cause damage, period. My other set were zinc & pass and powder coated by Matt, the coating fell off probably because the zinc coating wasn't prepared correctly prior to painting, I then shot blasted and powder coated, disliked the colour so sprayed with an aerosol can, but my Karcher hot water pressure washer fetches the paint off a treat Take your choice mate!

Hybrid_From_Hell Posted September 29, 2007 Author Share Posted September 29, 2007 Nige,The tyre fitter used a silicon pad under the tyre Erm is this now legal or do I just have to pay cash and hope nobody sees me Seriously I think the more I read on this thread the more liley I am to grab a tin of spray paint mask spray and then redo as and when, maybe the tin coat of paint won't "Chip" like stove (prev) or powder coat, but I do admire your "Coming Out" re the use of silicon pads and black rubber <cough> snort eh missus Nige Quote Link to comment Share on other sites More sharing options...
dollythelw Posted September 30, 2007 Share Posted September 30, 2007 have em waved at with a shot blaster before you paint them Nige - gives the paint a nice key, its still going to chip but it takes more abuse to do it Quote Link to comment Share on other sites More sharing options...
