Is FibreGlass or FBP best if storing under Pine tree sap?

Pine sap, and some other conifer saps, will tend to stain the gelcoat on fiberglass, and will raise welts in clearcoat. I got my car under my brother's spruce tree for a few days, within four months after I bought it new. Three years of washing, polishing and waxing have not yet rubbed out the little welts left behind.

Used to be worse before clearcoat, sap left on long enough would lift the paint. These saps contain small amounts of some organic chemicals used in paint thinners. Turpentine used to be distilled from pine tars.

Repairing the paint will likely cost more than trying to clean the fiberglass.

Nothing is safe under pine.

Full body paint will be easier to maintain over time than gelcoat fiberglass. However, I've lived in the South all my life and I would find a way to keep the pine sap off the rig at all costs.

Tree sap is terrible for paint, not to mention the TPO roof. I would cover it if it were mine.

sorry i cant answer your question but I gave nothing else going so I think I will blow smoke up your ying yang anyway. Dont park under a sap tree, it will ruin your new motorhome

Sunshield tarp over the top and down the sides a few feet.

I'm looking to purchase a new Jayco Precept 31UL and they just announced a Full Body Paint Option. Since I plan to store the coach in Prescott under some Ponderosa Pines I am concerned about which finish would be best in regards to the pine sap? Or doesn't it matter much? Or should I consider using a MH Cover to protect it?
Full Body Paint?
Standard FibreGlass GelCoat?
RV Motorhome Cover?

There's only one logical answer for you. COVER IT! If you're planning on purchasing a brand new unit and, it's going to have full body paint, there's no two ways about it, COVER IT. Not to mention what that roof on that new coach is going to look like in short order. Depending on where you live, i.e. snow, winds, things like that, you can get a swap meet style that will work great. By that I mean a galvanized tube frame and, a really good tarp held on with bungees or intertwined with nylon rope.

It's a cover. Not maybe the best but, none the less, it's a cover and, you won't have to contend with that pine sap and possible goof up that nice new FULL BODY PAINT and or that nice new roof. Good luck.

Sorry I cant answer your question, but a cover will certainly help protect your coach.

If you own the property consider having a carport installed to store the coach .For around $1500 you can have one installed and problem will be solved.
