How can I best waterproof textile and plastic roofs?

SONAX recommendation: clean convertible tops with SONAX Soft top cleaner. The highly active special cleaner rapidly and thoroughly removes even stubborn dirt from convertible tops. It can be used during the car wash without any problem: simply spray the wet top, let sit for 2-3 minutes and thoroughly rinse with clear water afterwards. Treat extremely stubborn dirt with a sponge during exposure time. SONAX Soft top cleaner does not damage original paintwork and does not cause tension cracks in plastic windows. SONAX Soft top & fabic water proof impregnation (Art. No. 310 100) seals convertible tops made from textiles as well as upholstery, carpets and textiles in the car’s interior. This product is also suitable for Alcantara. After cleaning, apply the impregnation to the dry top with an application sponge and spread evenly. Let dry for approx. 1 hour. The product refreshes the top’s colour and protects it against resoiling.

Basically, a polish only treats the car’s clear coat. This is approx. 30 µm thick. A very intensive manual application – e.g. with SONAX Xtreme Polish & Wax 3 – can “sand down” a maximum of 0.3 µm of the clear coat.
Nya eller polerade lacker:
Använd SONAX XTREME Liquid Wax; ett revolutionerande flytande hårdvax baserat på banbrytande nanoteknologi. Dess innehåll av högkvalitativt carnaubavax skyddar långvarigt mot vädrets påverkan och de finfördelade vaxpartiklarna arbetar sig lätt in i de fina lack­porerna, tränger djupt ner i ytans ojämnheter och ger en strålande glans. I och med detta förseglas lacken och ett extremt bra långtidsskydd skapas. Metallic eller vårdade lacker:
Använd SONAX XTREME Deep Gloss Polish; en mycket skonsam rengörings- och polerprodukt för alla lacktyper och lackerade plastdetaljer. Mikrofördelade polermedel rengör och polerar lacken, tar bort smårispor från maskintvätt och avlägsnar oxidhinnan. Högkvalitativt carnaubavax skyddar lacken om du inte hinner vaxa den med SONAX XTREME Liquid Wax direkt. Matta eller eftersatta lacker:
Använd SONAX Xtreme Power Cleaner; framställd för att effektivt rengöra nedgångna, repade och oxiderade billacker. Oxidhinnan försvinner och lacken får en jämn, skinande yta med optimal färg och glans. Även lämplig för lackerade plast- och vinyldetaljer. SONAX XTREME Power Cleaner är extremt lättarbetat. Högkvalitativt Carnaubavax skyddar lacken om du inte hinner vaxa den med SONAX XTREME Liquid Wax direkt.
Recommendation: SONAX recommends Xtreme Wheel cleaner full effect. It is a powerful, acid-free special cleaner for all steel and light-alloy rims and wheel caps.
We recommend SONAX XTREME Upholstery & Alcantara cleaner in the 400-ml aerosol can for treating stains in textile, velour and Alcantara covers. The powerful foam penetrates the fibres deeply, resolves dirt, and, at the same time, eliminates smell by binding smelly substances.
For this we recommend using SONAX Plastic restorer black or Xtreme Plastic restorer gel exterior Nano Pro The products restore the colour of unpainted plastic parts and seal the surface against aggressive environmental influences.
The SONAX Dirt eraser helps with polish residues on plastics: slightly moisten it and simply rub off residues. Tip: treat rubber and plastic parts with SONAX Xtreme plastic restorer gel Nano Pro before polishing the paintwork.
For the cleaning and care of leather parts (incl. leather steering wheels) we recommend using Xtreme Leather care foam Nano Pro. It is a high-quality foam care for the gentle cleaning and care of leather parts in the car interior, motor cycle clothing and other smooth leathers.
All SONAX windscreen washer fluids can be mixed. But: washer fluids for the winter do not optimally work in the summer and vice versa. The products are adjusted to the respective temperature ranges.
Also in the car’s interior plastic surfaces – e.g. in the cockpit – should be protected against fading. For this we recommend SONAX Xtreme Cockpit cleaner matt finish Simply spray on product and wipe surfaces.
