I noticed today that all the horizontal surfaces are rough. I don't think I parked under anything that I can remember and it does seem to improve with wax but not totally.

What are some good waxes for the fiberglasss surfaces? I usually use Macguires NXT on my other cars but don't know if that's good on fiberglass.

Clay bar first.

You will probably need to clay it first. So wash it in blue dawn soap. Then clay with good clay bar. Then wash again and seal with a high quality sealant.
Others will chime in with what they like to use. It's been beat to death on here. Anything from Zaino, to Macquires, to Rejex. It's all in what you like.
Do a search on here there are many, many tutorials.

You can finds lots more info in the Car Care section of the Forum too. Good luck.

I have successfully used NuFinish to get off sap etc. from the car's finish and make it really smooth - good luck

Clay bar the car first and then apply your choice of wax or polish. Being in AZ I would seek some shade rather than apply in direct Sunlight

Another vote for clay bar first.

Even before the clay bar, I'd try some bug & tar remover. If that seems to work, go with it first. Then clay, polish if needed, "wax" (I like Rejex but there are several good choices).

I agree with what others have said. Try clay bar then wax.

Nothing wrong with the NXT you are using on the other cars. I used NXT on the vette then changed over to Zaino. I like it better but NXT gives a nice shine too
