Our ROTWEISS products have established themselves in the areas of boats and caravanning.
The selection of the products depends on the condition of the surface. 

GRP / Gelcoat

For new or nearly new surfaces we recommend the ROTWEISS Paintwork Preserver or the ROTWEISS Deep Shine Polish for sealing.  By doing this, the surface is protected from environmental influences and thus prevents early aging and brittleness.
Apply the polish with a clean cloth in sections using circular movements. To polish it off, one should also use a clean soft cloth or polishing threads.

If the surface is weathered, yellowed or scratched use our ROTWEISS grinding and polishing pastes.

ROTWEISS Grinding Paste RUBIN (very strong grinding action),
ROTWEISS Grinding & Polishing Paste (medium grinding action)
ROTWEISS Polishing Paste (fine grinding action),
ROTWEISS Paintwork cleaner (very fine grinding action)
and as a sealant
ROTWEISS Deep shine Polish or ROTWEISS Paintwork Preserver

Since the Grinding Paste RUBIN has a very strong grinding effect, it is always worth trying initially to remove the scratches with the Polishing Paste. The Grinding Paste RUBIN might leave fine scratches behind. These can be polished off with the polishing paste.

Very important:
Use only a little of the product and work it in completely.
Do not allow the paste to dry on. If necessary, spray some water onto it.
For larger areas using a polishing machine is sensible.

Direction of movement:
From UP to DOWN and from LEFT to RIGHT
If you are applying the paste by hand you should make sure that you work the product in using strong, circular movements and for polishing-up always use a fresh, clean cloth again (ROTWEISS Hand Polishing Sponge).
By doing this you will prevent smears and streaks from the outset. Use the polishing agents sparingly – this makes the final polishing off easier.

For corrugated surfaces the grinding and polishing pastes can be applied with a root brush and subsequently rinsed off with water. 
Do not treat these surfaces with the Paintwork Preserver, as it causes danger of slipping.
Also plastic persennings can be renovated using the ROTWEISS Polishing Paste.

Tests on the under-water line of boats have shown, that the plant life growth progresses considerably more slowly if the surface is treated as described above.
The preserved surfaces are also easier to clean off again when they are dirty.
