Sorry, please note on the face of the gold mag above, the edge around the chrome rim is or was a sort of silver with some gutter rash, I spoke to the owner and suggested a 5mm gold pin strip, he said to do what I think looks best, I think it best to check with his wife too, ha. other options might be a bright red pin strip, black pin strip, or even the color I may paint the car with, light metallic blue, ???, 2 points of interest here are, which ever color pin strip is chosen,1, it can eagerly be changed, 2. painted edges is easy to fix future gutter rash,
Rear of the mag was oxidized throughout to a thin coat of gold paint, I lightly dry sanded ( 1200 grit dry.) and the thin old gold coat pretty much fell off,

Wipe the rear of the rim with thinners and paint,

Please note, I did not use any masking tape at all, I use “the controlled overspray method”, where I apply n/f to all over the face of the mag, any over spray settles on the applied n/f and is wiped off with the n/f residue “immediately” after painting. Or I cut out cardboard shapes to fit inbetween the spokes to block overspray spraying through the spokes at all, and or toilet paper can be slightly moistened with thinners and crushed or mashed into “packing” forced into the spaces between spokes, usually when I do the mash packing method and the cutout card board method, I can use them on the other 3 wheels to block overspray passing through the spokes,
Middle of the flat section in the rim, I tilt the angle of spray at the flat section so as to blow any overspray, out through the face, when using the n/f method, on a personal note, I hate masking up a mag. red arrows show a piece thin cardboard cut to shape, and be used with med pressure and guidance to carefully slide in between the tire and rim to stop overspray getting on the tire, yellow arrows show groove in the rim, that needs to be back sprayed to ensure overall coverage on both sides of the groove, please note, I wipe wet overspray off the cardboard every time I spray roughly a 150mm section, or it will drip on to the fresh paint. Please note, being able to rotate the wheel or rim on rollers, makes it so easy to overlap the paint on each section and maintain arm and wrist movement rhythm, stopping putting down the spray can and wiping the card board clean, pick up the spray can with one hand, and rotate the wheel or rim, 1/16 of a turn with the cardboard in your hand, position the card board, hold steady, with the other hand holding the spray can ready to lay the same spray pattern overlapping the last spray pattern three times, and three layers to build up a good coat without runs, I usually locate the air valve looking through the spokes, and rotate / spray, and spray sort bursts, and again rotate the wheel around 1/16 of a turn, until back to the air valve, please note, that is 48 x 1/16 turns, plus 32 1/16 rotations for 2 coats of acrylic clear, total 80 1/16 rotations,
Here is a quick sketch of a diy Mag roller set up, black lines show ??? 50mm x 150mm any wood drilled to suit, green lines show short lengths of dowel or broom handle pressed through holes, red lines show PVC or plastic pipe x 2, blue lines show where plastic pipe is fitted on the dowls and spins freely, maybe some bees wax as lub. Nice clean wood and plastic so you can clean your wheels in the kitchen,
So I spray 2-3 rotation with base coat color, x 2 -3, I am guessing about 50 to 60 micron thick coating, “without” filling in the very fine lines around both the face and the back of the rim, they look like press or machine marks pressed in the paint and chrome surface, to maintain the originality of the mags, pics coming, ((on the other hand I or you could spend some time to sand out the machine marks to get a flat mirror finish, again using the 1/16 rotation method promotes continuous even sanding, x3 each rotation clean off any sanding dust and change the grade of dry paper starting at 800, 1200 , 1500,to sand the rear of the mag super flat,) ) and remember to wipe the cardboard clean every time , and you spray again, right around the rim. also use a hot air fan to keep the mag and paint warm at all times, and quicken drying times = no runs, also after drying for a few hours I lightly dry sand with 1200 to 1500 grit dry paper in-between 2 coats of bass color, WARNING DANGER do not over heat spray cans in the oven with the mags, I usually carry small spray tins in my pockets to get it to body temps, or only place them just in the oven enough to get some heat from the oven, not the full heat that a mag reaches when drying paint coatings and n/f coatings, , and shake well before spraying , works for me, minus the hours of time taken to mask up 4 wheels this method is pretty quick also when painting I also focus on section the previously painted 1/16 rotation combined with lighting to see the reflection in each previouse section is evenly covered with a thin wet coat, very thin, no runs, also on these machine surface type painted wheels I apply the nu-finish in a parallel fashion or around the rim with the machine mark grooves, and remove the freshly cool residue in a circle-r motion around the inside of the wheel, finishing lightly a circle-r wipe, remembering the surface is still soft, my line of thought is I have already applied 2 coats of clear to try and fill in the machine marks or groves as much as possible, to get a flat shiny surface on the acrylic clear layer, than apply the nu-finish layers to flatten out the surface more, and still maintain the machine marks visually, but not be able to really feel them with finger tips,
Always keep the thinners and small piece of torn rag handy, after painting, ,
How much does spay canning 4 wheels cost, first I purchased 2 small spray tins of 150g at $10 each, on special and usually $13 each, my best 2 guesses at color matching the gold color, neither matched, and yes I should have took the mag to shop with me, I have since purchased 2 more tins at $20 which I am happy with the color match, I intend to use the miss matched colors as base coats, and the other 2 spray cans that are the correct color as top coats, and 4 x 150g should do the 4 mags, $40 dollars for 600g of paint, if I know the color required, eg ultra white, I purchase 2 x 350g cans at $17,50, and pay $35 for 700g, and have some left over, I also have a litre of un- thinned primer, $35 nice and thick to fill chips and scratches with a brush, and a small tin of plastic putty, $35, one spray can of clear, 350g, $12 - $15 usually does 4 painted mags, totaling about $50 in paint, to do 4 mags, Below picture shows some of my little wheel paint collection, sorry, I am having phone camera pics to computer probs, back asap,
Just one more point here too, (this is the scary bit), is from my experience of 10 years of trail and error is I have been applying paint and n/f over the paint, please note I have also painted “over the n/f surface , this hard to explain so my line of thought is to make an observation, that will be to polish a small alloy piece to gain a chrome reflection, , also a small piece of hardened steel (maybe a tow bar tongue) polished to a chrome reflection, coat them both with n/f, when that is cured spray paint a bright color over small section on each and when the paint is cured, apply more /nf coatings, spray more small patches of paint, please note in my 10 years experience I have done that heaps on many surfaces, I have never seen any reaction or fault, such as orange peeling, wrinkle, flaking, oxidizing, no etch primer, no undercoat primer, just n/f and paint, that is the scary truth, try it yourself,[/URL]
