- • WX Block & Seal Technical Paper
A nanometer is 10–9 meter – smaller than the wavelength of visible light. Particles that have a size of less than 100 nanometers are considered nanoscale materials. Interactions on this level are between the micro–scale and the molecular size range. At the nanoscale level new physical and chemical properties can be exploited. The microscopic contour of the surface plays a role in resistance to UV induced surface reactions. The result of a rough (on a microscopic scale) surface is that more surface area is available for UV exposure. In addition the “peaks” or high spots of the topography may present areas only a limited number of molecules wide. These localized areas are subject to a higher rate of photo–oxidation than the “valleys”. Presenting a smooth surface at the microscopic level reduces the rate of UV exposure degradation. WX Block’s nanotech particles improve gel coat surface microcontour and retention of UV protection for maximum effect.
WX Block & Seal System Application
Because your sailplane is a very special thing, please take a few moments to review these application directions to insure maximum performance from WX Block products. While there is nothing difficult about using the WX Block formulations, it is important to follow these simple procedures to achieve the greatest benefit.
1. Initial Washing
Wash dirty surfaces with a mild, non–spotting automotive type soap if required. If the surface is slightly dusty, a thorough damp wipe may be sufficient. Remove any heavy bug stains during the wash. Dry surface with clean non–synthetic rags, towels or chamois.
2. WX Seal Application
The purpose of WX Seal is to further clean and prepare the gel coat or paint for the subsequent application of WX Block. WX Seal may be applied by hand, or with a buffer for deep cleaning and mild scratch removal.
WX Seal Hand Application: (Preferred Procedure for Normal Cleaning)
Shake well before using. Apply lines of WX Seal to the surface covering the immediate work area. Using a soft, clean non–synthetic rag spread the material over the surface. Begin buffing with medium pressure and reduce pressure as the surface begins to shine. Repeat as necessary to remove bug stains or other imperfections from the surface. Use a clean rag for a final wipe down. Allow 15 to 30 minutes, depending on temperature and humidity before proceeding to the WX Block application.
WX Seal Power Buffer Application: (Optional Procedure for Dirty Surfaces)
Use a low speed (l500–2000 RPM) buffer with a good quality wool buffing pad. Be sure the buffing pad is clean and free of any residue which could scratch the surface. It is a good idea to use several buffing pads for an entire sailplane. The buffing pads may be cleaned in water and spun dry on the buffer if needed. (Take precautions to avoid electrical hazards). When using a buffer on a sailplane take great care not to heat the surface by concentrating in a small area or by using excessive pressure. Also be very careful when buffing in the vicinity of control surfaces and trailing edges so as not to hook the buffing pad on an edge and possibly cause damage.
Shake the material well before using. Apply lines across of WX Seal across to the surface. Begin buffing with medium pressure and reduce pressure as the surface begins to shine. Do not heat the surface. Repeat as necessary to remove bug stains or other imperfections from the surface. Use a clean rag for a final wipe down and allow between 20–45 minutes. depending on temperature and humidity before proceeding.
3. WX Block Application
Shake the container well to insure complete mixing of the material. Spread lines of WX Block across the working area. Use a clean non–synthetic rag to spread WX Block into a thin uniform film across the surface. Inspect surface from different angles to insure complete coverage. Allow to dry. Hand polish to a high gloss finish. If a second coat is desired for maximum protection, allow 30–60 minutes between applications, depending on temperature and humidity. Several extra coats on leading edges will reduce the severity of future bug sticks. WX Block may also be used for normal post flight cleaning and bug removal.
4. Frequency of Application
Sailplanes Stored In Trailers or Hangers: Apply WX Seal and WX Block at the beginning of the season. About mid–season rejuvenate the finish with another coat of WX Block. Use WX Block for post–flight clean–up and leading edge bug removal. This will also help decrease the severity of future bug sticks.
Sailplanes Parked Outdoors: Treat your gel coat with WX Block about every 90 days for maximum longevity. Every other cycle (180 days) follow the complete WX Seal and WX Block application. In severe conditions or to increase levels of protection apply more frequently.
- Test colored lacquer based accent stripes or sailplane ID markings for color fastness.
- WX Block creates a very slippery gel coat surface. Handle sailplane components with care after application.
Gap Seals, Wing Tape & Contest Letters: WX Block will cause reduced adhesion of gap seal tape, contest letters or wing tape if applied to the gel coat prior to mounting. If replacing or mounting new gap seals or contest letters it is recommended to adhere them before the application of WX Block. Put normal wing root and horizontal stabilizer tape in place before the application of WX Block in order to avoid reduced adhesion of this removable tape.
