Several weeks after my post above: I'm hoping there is UV protection because I am underwhelmed by the shine. It's OK on the sides, but no significant luster over what it was previously. I treated the somewhat oxidized roof 3 times, using the Aero 303 website recommended "method 1 for restoring gelcoat fiberglass" on the last two applications. It is satin-like at best when viewed head-on, probably more like semi-gloss when viewed sideways. Maybe another treatment, or another plan - don't know, Glenn.
Here is some info from the 303 Aerospace web site - note that it says a matte finish.
303® Aerospace Protectant 8oz.
Key Benefits
- Keeps treated surfaces looking new
- Prevents fading and cracking
- Restores lost color and luster
- Powerful UV blockers
- Anti-Static, repels smudges, dust, soiling and staining
- Matte finish with no oily and greasy residue
- Easy to use, simply spray on and wipe dry
I have yet waxed or 303ed but now that it is one year old perhaps it is time to do so? Also might help with the black water streaks running off the roof - that is probably a symptom from living on the west coast?
