WE DID IT!
This has taken weeks and has been a massive learning process. Huge thanks to Tomcat for help and advice.
First thing we did wrong was thinking grit blasting the wheels and then filling and sanding the imperfections would be a good basis to start from. What I thought was as low as I could go was in fact the original undercoat- the paint I used reacted to this undercoat and we were doomed to failure.
I paid a pro to acid strip them- he did one while I waited, only took five minutes to remove the paint I had put on and take them back to silver base metal. That was a bit soul destroying as I had spent a few hours trying to strip one with paint stripper.
Once we had the bare metal we sanded them down with wire wool and filled any blemishes. Two layers of undercoat were then sprayed on and sanded back each time- all coats of paint have to be very slight and not piled on. The undercoat was a 2k product and required a hardener, four parts paint to one part hardener.
Two costs of basecoat were then applied and allowed to go off. This was another 2K product, two parts paint mixed with one part 2K thinner.
Once we were happy with the basecoat we applied the clearcoat lacquer. Two parts clearcoat to one part hardener. Two coats were applied and the wheels left in the sun to dry.
Products used are in the links below:
Wheel Paints Lacquer pack This is enough product to probably do twelve wheels!
VF Silver (Solvent) 0.5L will do four wheels easily.
Anthracite Silver (Solvent)
Ended up using 1L of this as we have ended up doing them all twice.
2K 4 1 Primer A very quick drying primer that sands back very smooth. The Pre-Clean (Solvent) was a good product for removing greasy finger prints.
Superfine Pads Pack of 10
These were very good for sanding, not too abrasive.
You may be thinking the above adds up to a lot of money and it probably does but saving money wasn't my main reason for going DIY. I'd previously paid a lot of money for a refurb that lasted six months before the paint started peeling off. I just wanted the job done properly and I knew my Dad and I could do it if we tried hard enough.
I re-used the BBS bolts after cleaning them up and polishing them- not a mark on them. No I don't Xray vision and can't see the internal fractures or molecules separating. Seriously do you think refurbers replace the bolts or re-use the originals? lol Torqued them up to 18ftlbs- thanks Pangster for your help there.
Here are the finished results- to say I am chuffed would be an understatement!
I am confident that once a set of wheels were acid stripped we could get them finished and dry in two days- not that I am looking to do another set anytime soon.
