Has anyone used or heard of a product called "soystrip" made by newmat chemicals?
After being "burned" by peelaway I'm wary, but I still need to finish stripping the bottom of the outrage.

I used the Interlux stripper in the green can on mine. Roll it on, let sit for about an hour, then scrape off the paint with a window scraper.

Can any of these strippers be used without the risk of damage to the gel coat underneath?

Mine has the thin and patchy remains of a coat of bottom paint and I have been pecking away at it with 400 then 600 and finally 1500 wet paper and followed with polish. It takes time but it seems to leave the gel coat with a mirror finish as long as I don't get too earnest with the heavier grit.

Any help will be appreciated.

I used the intelux 299e two weekends to remove the bottom paint from my 13.

The stripper softened the two layers of paint in about 15 minutes and I was able to remove it with a plastic scraper. It did leave the primer on the fiberglass that I removed by applying a second coat of sripper and scrubbing with a green scotch brite pad. After that I wiped down the are with the intelux fiberglass cleaner recommended on the can.

I used about a gallon of stripper, two quarts of the cleaner, two scotch brite pads (cut up into 2x2 pieces), and several rolls of paper towels.

My only reccomendation is to mask off the areas of unpainted gelcoat because the stripper will affect the celcoat if left to sit on an unpainted are for any period of time. I will have to check the boat this weekund, when I sand the bottom to get out the scuffing that was done to adhere the primer, to see if there was any permanent damage to the gelcoat.

george nagy at al,

I just called the 800 number for Franmar and the lady graciously offered to send me a 4 ounce sample to try. She said Soystrip is guaranteed not to hurt the gel coat and is biodegradable and non-toxic. She said you can pour it on your hands without any akin irritation.

I sould get the sample late next week and will post the results after I have tried it on a small area.

I promised to post a report on Soy Strip but Tropical Storm Henri has made me put my maintenance plans on hold for a few days.

I got the sample and the instructions look fairly straight forward and I'm anxious to see how it works.

More later.

Did you get "burned" using the marine peel-away designed for bottom paint, or the regular version you get at Home Depot, etc.?

I tried it today on a small (4x8 inch) area under my '97 Dauntless 15 swim platform. Boat has one coat of green bottom paint. I applied the SoyStrip as thick as I could- probably about half the 1/8" that the directions suggest. I waited an hour and scraped it off w/ a wood scraper (I'll use a plastic putty tool next time). The paint came off fairly easily, and did not damage the Gel. A little of the 3M combo cleaner/wax made it look like new. The Soystrip is safe ( to skin, lawn, dog etc.) but the stuff you scrape off is not. I definitely recommend this product.

Glad to hear of your good results using Soy Strip.

T.S. Henri has blown over and I plan to try it on Monday.

I promised to report on Soy Strip. I tried the sample on a small area of the transom and it really works as advertised.

The problem is that my 1966 boat seems to have been painted over the gelcoat and I took off some white paint as well revealing a yellowed area of gelcoat.

My boat has a very well worn thin and spotty coat of bottom paint.

Anybody got any ideas for removing the anti fouling other than successively finer grits of wet paper? I've done a little that way but it is really tedius.

Thanks in advance,

Why not use the soy stuff? You said it worked?

I have paint under the anti fouling which is also removed by Soy Strip. I don't want to have to have the entire hull repainted if I can avoid it. To have it done with a paint like Awlgrip professionally is an expensive proposition.

Still looking for ideas:-)

After a little shipping snafoo I finally got my own bottle of stripper from soy strip. I tried it last night, leaving it on only for a half hour and it did soften the paint a little. I will try after an hour or so this weekend and post results.

Try a can of Easy-Off oven cleaner. I find the original formula, not the "No odor" works best.
Removal is easiest with a power washer, but don't reapply until the surface has completly dried or the cleaner will be nutralized.
good luck, jim

I've just finished removing a thick coat of Brown paint on the inside and outside of my 69 Nauset. I started out with West's marine version of Peel Away. That worked OK but was quite slow, required a lot of grunting with a plastic putty knife and left so much on the boat that I had to go over it again with Easy Off and a 3M stripping pad with handle. So I quite using the Peel Away and had good luck with the Easy Off and 3M stripping pad.

Now I'm looking at some quite faded and oxidized white and blue gel coats. I'm trying various brands of machine buffing compound while I'm talking to myself that it doesn't have to be that nice, that it won't catch any more fish, etc.

Anyhow I'd recommend the Easy Off with the 3M stripping pad with a handle.

Just a quick update.

I tried two applications of soy-strip on the many layers of paint each time only letting it set for an hour. I'm still a little bit scared of chemical strippers after my peel-away experience. I'm not sure but I think the gelcoat on my 1987 outrage might be slightly softened by soy strip too. I'm probably going to switch to oven cleaner now that most of the paint has been thinned.

I bought a gallon of SoyGel, which the company told me is not quite as strong as SoyStrip. I bought it for removing varnish from the mahogany I could save from my Sakonnet RPS and console. IT WORKS LIKE A CHARM. I let it sit for 30 minutes and many years of varnish peeled right off. No fumes or gloves and it cleans up with water and a scrubbing pad.

I will never go back to the toxic stuff I have been using for years.

One question. Are these strippers any good for bottoms that were prepped with an epoxy barrier coat?

I don't have a clue as to that one.

Try their website at: and ask customer service. They have been very helpful to me.

Hi. I've used a product called soysafe from to strip many layers of paint off my kitchen cabinets. I think it would also work on boats as well. Completely non-toxic...I didn't even have to wear gloves and it has a delicate citrus smell and was very gentle on the wood. I found it to be quite economical...two gallons for around $72 with shipping. Since I was stripping vertical surfaces, I applied the stripper, then laid newspaper up against it and brushed on another coat of stripper over the paper. I left it on overnight and it stripped clean easily with a putty knife. Sometimes the ink from the paper tranfered onto the wood, but it was easily sanded away. If that's a concern you could always use unprinted newsprint. Anyway, I hope you'll forgive the intrusion since I didn't use it on a boat but I thought the information might be useful to you. Happy boating!

I have used Franmar's "SOYGEL" on several applications on my boats, and other home projects. I THINK IT'S GREAT!
"SOY-STRIP" is supposed to be stronger, but I have never used it.
The most success I have had is to apply a thick coat, and cover with some sort of plastic to prevent drying: such as saran wrap(small projects), or opened trash bags(larger projects), or cheap plastic drop cloths (for huge projects).
I generally let it sit overnight, and then power wash clean, or scrub with a brush and diluted simple green and rinse.
I have removed thick built-up coats of varnish, paint, cetol, oil-based and water-based paints etc..
Little or no odor, does not harm skin, comes off clothes, really user friendly.

My suggestion: Roll it on with a heavy knap roller, as thick as possible, and then cover with disposable drop cloth that would be taped in place (not easy when you're doing the bottom of a boat!!)
The key here is letting the gel work WITHOUT drying out.
Let sit for overnight if possible. The longer it sits (wet) the better.

Then power wash or scrub with detergent and rinse.

(This could be a ecological problem, NOT with the SOYGEL, but with all the bottom paint[toxic stuff])

I've been recommending this stuff for the past couple of years. It nice to read that some others have been using it too.
