Default 303 Protectant for the gelcoat??

http://www.303products.com/shop303/i...protectant.cfm

Has anyone used this product for the exterior of the boat, apply it on top of the wax??

A friend of mine has a motor home with FRP sides and says he applies this stuff twice a year to the whole unit, and washing it is now simply a matter of rinsing it off and all dirt comes off.

I can't help but wonder what it would do to a boat, it says it is fine for gelcoat etc...

Has anyone used it for this purpose?

Sounds like it could save a lot of waxing by applying this on top of the wax a couple times a year. Apparently it is just spray and wipe.

My friend has a blue colored hull that was pretty oxidized and he uses it on the hull a few times a year when he does not feel like hauling the boat out and waxing it. It really makes it look great again.

We used it on our travel trailer - fiberglass sides, awning, tank covers (ABS?), just about everything exposed to the sun. I think anything that blocks the UV from hitting the gelcoat would make it last longer and help prevent chalking. Isn't it the damage from UV which causes the chalking in the first place?

I have not tried it on the CC as I gave the last bottle I had to the guy who bought my trailer which was before I bought the CC.

As to putting it on over wax, read the FAQ on the 303 web site.

does 303 aerospace protectant always work on fiberglass

In reading the directions on their website, it does list fiberglass RV's & boats as one of the uses.

I use this product on my boat on the seats mostly and the dash and I can honestly say it is a good product. Not sure of how it works on gelcoat.

Don't use it on the boat but I do use it on the tires and any rubber gaskets on the motorhome. Good stuff.

love it on vinyl and plastic radomes, antennas and such - keeps them from turning yellow - but too fragile and water soluble for gelcoat for me...

I have no experience with it but I am always suspicious of waxes and similar products that claim UV protection. ANYTHING you put on your boat will provide some sort of UV protection but I find it hard to believe any of these products provide a measurable level of protection. Think about the the thickest, greasiest, nastiest sunblock you have ever used and how that needs to be re-applied every few hours. I burn really easy and often thought I would apply some 303 or something else that claims UV protection to half a sheet of clear plastic and lay it over my arm or something to see if there was a difference.

You are comparing your skin to gelcoat? There are plenty examples of UV protected/stabilized plastics.

303 is great stuff, but is not the way to protect gelcoat. Any spray-on product such as this will wear off relatively quickly.

Cut to the chase and polish/wax the boat. There is no substitute for a good coat of wax/polish.

Agree, For a quick shine--like you might want to sell a boat?--the 303 on gel coat may make it look good. But Colonite Fleet wax or similar products are going to give better protection for the fiberglass gel coat.

I use it on vinyl and rubber.

But I have been able to keep gel coat new looking for years using 3m marine wax. The trick is to stay on top of it and don't let it get bad looking in the first place.

Actually, I am comparing products that are applied to skin and plastics. There is a difference between designing the chemical structure of a plastic product to resist the ill effects of UV light and advertising a "coating" that can be applied over a surface and retain any long lasting UV protection. UV protection and optical clarity do not go together. My skin in the test I described woul just be a convenient and unfortunatley sensitive UV meter
I would just like to see some of these claims tested and verified.

PS. My UV protection comes from a full Sunbrella cover.

Sounds like great advice. I have been doing this regularly, three times last year and once this year using Carnuba wax and it has maintained relativelly well with using a mermaid wash with carnuba wax in it.

Looks like 303 is a great product for vinyl and rubber etc. but not the gelcoat.

thanks for the opinions guys.

I wash my camper with Mop & Glow. It is easy and helps keep the shine.

Susposedly 303 Protectorant, not only has UV inhibiting properties, but also helps to prevent plasticizer evaporation/loss. It is used on clear vinly, and seems to retain optical clarity.

303 has a series of photos of materials which one side was sprayed with 303 and the other not--and after thousands of sun exposure, the side which is coated, does not show detiorration. The unprotected side is badly detiorrated. Of course this could be faked, by completely covering one side. But I tend to at least give some credance to their claims, and use it on vinly, rubber and simlar products on a regular basis.

Never heard of this one, you are talking about the sealant, right?
