Bob, as others have suggested your trailer is pretty new and Bar Keepers friend may be a little bit harsh on your nice gelcoat. 3M makes a Marine Clean and Wax that works really well at taking off stains and streaks and although the small bottle will set you back $14 - you can do the whole trailer with it a few times. As Donna suggest using a good wax - marine folks seem to recommend using a good carnuba paste wax on gelcoat. I have used a Meguiars one for the last couple of years that seems to do a pretty good job.

If you're looking to remove all the gross nasties, but still have a good gelcoat underneath. I'd suggest buying 30 second Outdoor Cleaner (available at Lowes, etc). Put it in a pump spray container (like you use to kill weeds), spray the entire trailer. Let sit for a few minutes then hose it off. Wash with a good car wash soap, dry... the use Mequires Flagship Wax.

Yes BKF is slightly abrasive. So is rubbing compound, wet&dry sandpaper which is also good at removing oxidation from fiberglass if used properly. BKF contains oxalic acid which is what enables it to remove rust stains that are absorbed into the fiberglass.
As for using 30 second cleaner, what does it do to the decals on the trailer.

You mention that RedMax is now called "Zep." I checked the Zep webpage and they show 6 types of Zep Sealer. You don't happen to know which is the product formerly known as RedMax.

The secret is to use the Google search entry box at the bottom of the search pull down (top of page).

Yes all the items you mentioned are abrasive but all to varying degrees. The OP has a pretty new trailer and if its been cleaned and waxed regularly since it was new it a pretty good bet it doesn't have a big oxidation issue or need a product with much if any abrasive agents in it to get it shining brightly again or get any bug/blood stains off of it.

I have used BKF as well as some pro type compounds & off the shelf consumer based fiberglass cleaners and wax combo products over the years on different fiberglass items. I would suggest that BKF is somewhere in the lower middle in regards to how abrasive it is. One things for sure, the fewer times the gelcoat finish is subjected to an abrasive cleaning the longer it will last. Way better/easier to keep it protected with a good wax right from the start.

The OP asked simply has anyone used it and if they liked it or not, no qualification about what type of fiberglass or what they wanted it to accomplish. I posted in #6 that BKF works well to remove rust stains from fiberglass. My point was for information, that one thing that BKF does is to remove rust stains from fiberglass.

No problem my comment were also for information purposes only as well, just in case someone thinks there is no down side to giving a trailer a good rub down with BKF.

Great conversation! Do you know if 30 sec outdoor will clean the oxidation off my Scamp?

Glad to see this thread. I used BFK last summer on my Trillium, rinsed well and used 5 coats of ZEP. It looked great!
This spring, it looks awful. Peeling, flaking, chalking. All on the top half. What could have gone wrong? Maybe dried too fast?
I would love some ideas.
Thx

The website had me howling, most of the instructions had you keeping the items wet for much longer than 30 seconds. Does anybody have an idea of what is in it? WHIMIS trained minds always wonder what we are working with.

If you are saying that the peeling etc all takes place above a point of demarcation, eg belly band, that would make me think that the top had some sort of material appllied to it previoiusly that the bottom didn't. What comes to mind is the waxes that had silicone in it to make the water bead. There have been threads where people have used WD40 or similar materials on the www to try to restore the look of gel coat.

If that is the case I'd be tempted to test different cleaners and or solvents to find one that works. Such as TSP, acetone, 3M fiberglass prep, alcohol, maybe even the ZEP stripper. Did you use the sealer first? Or just straight wax?

Hi Roy, Finished that Boler yet?
I doubt there was any finish of any sort on the Trill. It was really chalky when I got it and the finish was well worn where a plastic tarp had been put on over winters. No, I did not use a sealer either. May have to try that this year. So disappointing.
The areas that got the most sun show the worst failure.
