Stains on front cap - 290RLT

[DHolder]

I have some brownish stains - almost like drops on the top side of the front cap of my 290RLT. I've tried black streak remover, goof off and simple green with zero success. Any recommendations on how to clean stains from the front cap would be greatly appreciated. I believe it is made from some kind of plastic rather than fiberglass like the rest of the camper? I also posted this in the maintenance section, but got only 1 response...

I've had good luck with turtle wax bug and tar remover.

I use Nufinish as a good stain remover even though it is intended as a paint protector, like wax.

Hi

Dholder, are they a very small perfect circle about 1/16" , dark brown and an absolute pain to remove??
If yes then you have what's known as artillery fungus or shotgun fungus. Bet youhave a cedar or pine mulch bed close to your camper. It's like a spore that the mulch shoots toward the light, or in your case a bright white surface that reflects it. I had a nightmare with my last camper. Hundred of them. I also found that if you picked off the hard top and then used NuFinish scratch removal cream from the auto store you can get them off but it takes time. My last camper was an aluminum side TT. I now have a fiberglass gel coated 5th wheel which I have waxed. They come off much easier if you can get a good coat of wax on there. Also, get rid of the mulch. Go to recycled rubber.
Hope this helps. If that's indeed what you have but sounds like it. Good luck!!!

Was it protected with Diamond Shield? I've noted lately, some front ends have an Algea growth under the "shield", which must be removed (3-5 mil film). Not an easy task.
