Compounding & Polishing with Aqua Buff

1. Buffing Pad: it is critically important to link the correct buffing pad to each Aqua Buff product. We advocate a tufted wool buffing pad for fast cut compounds like Aqua Buff 1000 or Tuff Stuff. For polishing with Aqua Buff 2000 or GlossMaster, we recommend a fine polishing pad.   A foam pad can be used to get the ultimate shine.

2. Amount used: we find that most users apply too much compound and polish. Dab on an amount similar to a poker chip (about 3 cm across) for each square foot (30 cm) to be polished.

3. Spray bottle: Aqua Buff 1000F/W and Aqua Buff 2000 are sold as concentrates. The person doing the polishing adds water by spraying a mist onto the part. The buffing pad captures the compound/polish, and also the water. When the part appears dry, add more water with the spray bottle. As long as a milky liquid appears when the pad captures the water additional polish is not needed. Aqua Buff Tuff Stuff and GlossMaster do not require additional water.

4. Heat: a significant benefit of Aqua Buff is that the sprayed water helps keep the surface cool during buffing. Heat can cause distortion to appear in the surface.

5. Buffer: we recommend a 2400 rpm commercial buffer. Wiping by hand will not create the necessary speed and energy to buff. Compound at full speed, polish at half speed.

6. Surfaces: Aqua Buff works on gelcoat, Duratec and other composite surfaces.

7. After buffing: wash the surface with soapy water to remove any leftover polish.

8. Sandpaper grit: a common question is- what final grit of sandpaper do I need to use? The answer will depend on the hardness of the surface (harder requires a finer grit) and the quality of the surface required. For most gelcoats, a final grit of at least 800 is recommended.

Aqua Buff 1000F is FAST. It can be too aggressive for soft surfaces, leaving swirlmarks. It is a grey-white color.

Aqua Buff1000W is a blue-green color. It works very well on most surfaces, but can leave a blue haze on oxidized gelcoat or white gelcoat.

Aqua Buff 2000 is a polish. It is used to remove swirl marks from compounding, or to re-shine oxidized gelcoat. Aqua Buff 2000 is a white color and does not leave a haze.

Tuff Stuff and GlossMaster are used when the polisher does not want to use a spray water bottle. Tuff Stuff is aggressive, and GlossMaster leaves a fine, glossy surface.
