I mentioned in another post that I was refurbishing my 5 spoke alloys and some members wanted to know the methods I used, so here goes !
This was the wheel at the start, corrosion and chips around the rim and centre cap.
And these are the materials I used, all from Halfords. This was enough for all wheels, plus wet and dry 120, 1500 and 2500 grade sheets.
First carefully remove any balance weights from the rim and the centre cap, push it through from inside. All of mine had missing lugs. Make a mark on the tyre to remind you where to re attach the balance weight at the end of the job.
I used the rotary abrador in an electric drill to remove the loose flaking paint and get back to bright alloy, and then 120 grade wet and dry all over the rest of the wheel. Dont use a wire attachment over the outer surfaces, it scores the alloy too deeply. i used an angle grinder very gently where the rim was distorted by kerbing.
Despite my pevious comment...I did use a wire attachment to clean out the inside of the wheel nut wells.
And after 30 mins or so of hard work you get to this.
Then mask off the tyre, I used the blue disposable paper roll type stuff they sell at Halfords, I scored the shape of the tyre rim into the sheets of paper and cut out the shape with scissors, then tucked the edges neatly behind the rim with a scoring knife and taped down securely.
Then wiped down the whole wheel with white spirit
And lightly spray in the exposed alloy areas with the etch primer (green tin) which apparently reacts and bonds well to exposed metal.
This dries quickly, 30 mins or so. After that start building up the layers of the filler primer using the usual aerosol techniques of a steady distance and keeping it moving and overlapping each pass by 50%. add extra layers to any imperfections/scuffs/chips.
Then leave overnight to dry hard. Next day, flat it down with 1500 wet and dry using plenty of water. You may have to go down to 400 grade where there are imperfections. When youre happy with the finish, dry it off and give the wheel an initial light coat of the wheel silver aerosol. This acts as a guide coat and will reveal any imperfections, its annoying after all the care taken so far but there almost certainly will be some. Allow this to dry hard before rubbing down with 1500 or 2500 grade wet and dry with plenty of water. When youre happy, give it the final covering of wheel silver, as before taking your time to build up the layers. It should be starting to look good.
When thats completely dry, apply the heavy duty lacquer. Be carefull as this stuff tends to run easily. Dont panic if it does as when its dry they are hardly visible. The lacquer takes quite a while to go fully hard, so dont be tempted to move it or remove the masking paper. When it is fully hard after 5/6 hours you can re-insert the centre cap/ I had to glue mine in using "no more nails" Which works quite well, any excess wipes off with white spirit.
the end result.
