After being given the notion to clean the car by Singvogel, more like shamed into it, I’ve given the 320 a good clean. Full wash with AG Conditioner, then used my clay mitt to get rid of the rash of tar and debris from the lower flanks and arches. Any heavy tar had a treatment with AG Tar Remover. I’d previously checked with AG that this wouldn’t invalidate the guarantee on the LifeShine and they said not. Then rewashed, dried and a coat of AquaWax to bring the shine/beading back to standard. Also got under the bonnet, a disgrace really....washed and rinsed then dried. Nothing too in-depth. Considering this is an 8 year old car with 81K miles on the clock, I’m really pleased with how it turns out.
