Last week we covered the exterior detail for this classic BMW E30 325i. This week features the work carried out on the leather interior and the wheels.
The interior of the car was quite dirty, the cream leather seats were quite discoloured. With the exterior now looking very nice the interior was even more noticeable! I knew it was going to take a while to bring the seats up to scratch, but that just makes the ‘before and after’ even more satisfying! – Master Detailer, UDS
Beginning with the rear seats, Valet Pro Leather Soap was applied and worked in using a Valet Pro Large Sash Brush. Leather Soap is a deep cleaning solution for heavily soiled leather. The active ingredient gets to work deep down to lift contaminants out from the grain. The soft bristles of the Large Sash Brush give enough bite to help remove the dirt and grime but won’t scratch the leather in the process. This procedure was followed for all of the seats until they were once again, clean and cream! To protect the leather from becoming soiled Gtechniq L1 Leather Guard was applied. Leather Guard forms a tough, abrasion resistant coating which prevents dirt from sticking on to the surface of the leather which helps to stop the leather’s finish from being eroded.
The floor mats were all removed and washed using Meguiar’s Carpet & Interior Cleaner which was sprayed directly on to the mats. The solution was then agitated using a Valet Pro Leather Brush ‘For Life’ to ensure the cleaner penetrated right through the fibres. The mats were then rinsed clean and allowed to dry before being coated with Gtechniq I1 SmartFabric Coat, a water repellent sealant that helps prevent staining from mud, drinks, etc.
The glass was cleaned using POLISHANGEL Cristal Agent glass cleaner. The dash was cleaned using POLISHANGEL Intimate, a cleaner for plastics and rubber which gently removes old dirt, dust, fingerprints, etc., from the surface leaving them clean with a satin sheen. Then POLISHANGEL SnowCake Interior Dressing was applied.
SnowCake has a UV protective factor of 60, so it works very hard to protect black dash and trim from fading and cracking. It leaves a natural satin sheen which doesn’t attract dust and also leaves a really nice marzipan smell too – the E30 smelled good enough to eat by the time we’d finished! – Master Detailer, UDS
The BMW wheels were in need of refurbishing back to factory standard in order to complete the look of the car.
Having the wheels refurbished was a must considering how much work had gone into the rest of the vehicle’s appearance. It’s vital the refurbishment process is completed properly and to factory standards. Trying to spot repair damage simply leaves weaknesses and it doesn’t take much for normal wear and tear to quickly erode these ‘touched up’ areas. – Jez Gilman, Ultimate Finish
Initially the wheels and tyres were inspected for wear, tear and damage and found to be scuffed and in places the lacquer was peeling off. The weights and the valve were removed and then the wheels were then placed in a non-acidic chemical solution to strip off remaining lacquer, leaving the wheel completely bare. After several hours the wheels were removed from the chemical bath and thoroughly rinsed to remove the residue. Once dried the wheels were they were low pressure bead-blasted to remove the scuff marks, making the surface pristine once more.
Next the wheels were passed through an oven to bake out any trapped air, preparing the wheel surface for initial primer powder coating. The wheels were then returned to the oven to cure the primer. Subsequently the wheels were transported via conveyor belt to a sealed booth for professional lacquer application. Powder lacquer was applied to the face and the inside of the wheel to provide comprehensive, durable coating which resists salt corrosion, brake dust deposits, etc. The wheels were then baked a final time to cure the lacquer.
Once the wheels had passed quality control inspection, tyres were refitted with new valves before being balanced. They were then wiped with Gtechniq Panel Wipe to ensure they were completely free of any oils and residues before being protected with Gtechniq C5 Alloy Wheel Armour.
Once the wheels were returned to the studio, they were carefully wiped down with Gtechniq Panel Wipe to ensure that they were completely free of any oils and residues before being protected with Gtechniq C5 Alloy Wheel Armour . Finally, before re-fitting onto the E30 the tyres were dressed with Swissvax Pneu to leave a soft, natural sheen.
The 325i was now looking back to its original best and the customer was mightily impressed when he collected it a week after originally dropping it off – even more so because it wasn’t raining, so he really could enjoy driving it home!
