4.6.2. Preservation of a paint and varnish covering
It is usually recommended to update an old covering and to protect new, applying on them protective medicines two or three of time a year. At the same time gloss keeps longer and long-term protection of a covering improves. The majority of protective medicines and means for cleaning of a paint and varnish covering are quite aggressive. Therefore never work under direct beams of the sun. Otherwise chemical compounds of polish "will stick" to a paint and varnish covering.
