GELCOAT FIBERGLASS
A Blotchy or Streaky finish
A blotchy or streaked appearance is what can occur when:
- The user waits before drying the treated surface (as one does with wax but 303 is not a wax and not used like wax).
- The user uses way too much product (common one should be able to do a 40` fiberglass RV the first time with no more than 1 quart of 303 A. Protectant).
- The user continues to use the same drying cloth to "wipe dry" after that cloth has become damp with 303. A 303'd surface cannot be wiped dry with a damp cloth.
The correction for a smudgy, blotchy appearance (brought about by using too much 303 and/or then not wiping the surface "completely dry" before the water in the 303 evaporates) is:
- Take a clean, absorbent cloth such as an old towel. Fill a bucket 2/3 full of clear water. Soak the towel in the bucket, then wring out about 2/3 of the water. Using the wet towel, wipe a 2' x 2' area of smudged fiberglass, getting that area wet with water.
- Then, with a soft, clean, absorbent, DRY cloth, wipe that area completely dry. What happens here is the water causes the unabsorbed, unbonded excess 303 polymer on the surface to instantly go into solution so it's easily wiped away. The finish left after this is the beautiful, glossy, repellent finish expected with `303'.
- Reapplication: Spray on, then immediately wipe completely dry. This process is much like "Windexing" a window, but takes less product. On a fiberglass RV, the caps start to fade first. It's necessary to redo the sides once for every 3-5 times you do the caps.
