For future lurkers who might be interested in the answer to my question.

Just returned from a place that sells new and used boats. There were quite a few used boats on trailers, probably there...

Will check it out.
Thanks.

West 207 hardener is also rated as not having blush.
Thanks.

Thanks Larks.

I do intend to use PeelPly when applying the cloth but only after my tests on scrap plywood come out 100% good. If that works out, it will reduce epoxy use minimizing weight while...

Agree. Testing on scrap plywood is exactly what I'm doing prior to glassing my boat.
Thanks.

Yes, in the "Epoxy Basics" book by Russel Brown that I just purchased, he mentions that 207 hardener does not have amine blush issues. West Systems also mentions the same thing in their 207 ads. I...

Thank you for your perspectives.
I think sanding the pre-coat will make the cloth easier to slide around than on bare plywood. But that's just a side benefit. Main reasons for me to pre-coat are...

Other than the extra work, I think the pros out weigh the cons for pre-coating for a novice like me. Guess for pros, it's needless extra work.

By the way, Russel Brown in his youtube video said...

I'll wait 7 days after pre-coating. Then remove the amine blush using the scubber and water. Next day when dry, I'll dry sand to remove the hairs and get a keyed surface. Thanks.

Thanks for taking the time to advise. Appreciate it.

I'll wait 7 days after pre-coating before I sand. I've decided to pre-coat to minimize the chance of air pockets forming under the cloth due to outgassing, and also to prevent epoxy starvation due...

I'm using West Systems epoxy. I remember reading about being able to dent the epoxy with a thumbnail to allow recoating.
Thanks.

Extra work is totally not a concern for me. If I "wet" sand the pre-coat the next day and then apply the cloth the following day, is that still considered "green"?

I'm thinking that "wet" sanding will eliminate the need to wait a week for full cure to avoid green epoxy dust in the air. I will of course be wearing nitrile gloves while wet sanding.

After the pre-coat epoxy dries hard, I think I'll wet sand to get rid of amine blush instead of using a green scrubber. That will also sand the epoxy in prep for applying the cloth. Or is just...

I'm going to let the pre-coat epoxy get hard, remove any amine blush, sand and then apply the cloth. Dry hard pre-coat epoxy will make it easier to reposition the cloth to avoid wrinkles.
Thanks...

Thanks for your perspective. I'm going to let the pre-coat epoxy get hard, remove any amine blush, sand and then apply the cloth. Dry hard pre-coat epoxy will make it easier to reposition the cloth...

Thanks for your always helpful advice Kevin. I've decided to definitely pre-coat with epoxy to minimize the chance of any bad air bubbles lifting the cloth. The extra work is a non issue for me...

Jon boat, not a canoe but I get the idea. Thanks.

Please see my reply to nrs5000.
Thanks for the help.

I thought that rinsing using a garden hose would be necessary to get all of the amine blush off since using a green scrubber is recommended. I assume that you both scrub with a green scrubber but...

I did a test and fiberglassed a scrap piece of plywood at noon. Applied PeelPly on top. Squeegeed the surface and it was very smooth with the cloth and PeelPly fully saturated but all excess epoxy...

Thanks. I just bought and downloaded a copy.

I've read much about having to use green scrubbers to wash hulls that are fiberglassed using epoxy, to get rid of amine blush. (cured epoxy)

Since boats are normally built indoors, often in...

Where did you buy Epoxy Basics for five dollars from?

Yes, extending the tongue is one of the options I'm investigating.
Also, if a trailer is narrow and my 46" wide (bottom) jon boat has to sit "above" the fenders, the height of the boat's bottom...

I've seen several youtube videos where the tow vehicles are submerged in the water. We can't afford to lose our Odyssey by having it submerged in salt water.

I'm not concerned about the...

Thanks for the additional info on your boat's setup and for the slippery bunk covers link.

So far, without fiberglassing the outside of the hull and painting the entire boat, the boat weighs about 180 lbs (bare without the motor mounted). When the boat is completed, I'm estimating that...

BTW, what are the hard plastic covers made out of? Any links to samples? Thanks.

That is quite a boat in the picture. Your van looks small in comparison. The stern of the boat looks to be quite high above the ground, like about 3.5 or 4 feet above the ground. I'm surprised that...

Our Odyssey is front wheel drive so it will be better to have the trailer hitched to the receiver on the back. Thanks.

Thanks Kevin. I will do that.

Last night I made a drawing using Sketchup. A trailer with 3 feet of tongue extending beyond the bow of a 12 foot flat bottom jon boat. With the trailer on level...

My plan is to epoxy the cloth like how Russel Brown does in his youtube video. Then apply the PeelPly over it. Will strive to have the cloth correctly saturated before the PeelPly is applied. I'll...

I'm thinking that just the weight of the vehicle can be enough to have it slide into the water since the boat (any boat) will already be floating at that point. The trailer will be fully submerged...

I've watched Russell Brown's youtube video on fiberglassing hulls. He is a master of fiberglassing using epoxy.
One thing that he did in that video was quite different. He wrapped the bottom cloth...

I haven't seen any jon boats which is why I'm building mine.
Regarding how deep am I willing to drive the trailer, I don't want our van's tires to go over slippery moss and have our van slide into...

Lower would definitely better for launching.

But what is the typical height in inches, that the bottom of the transom is above the ground when on a trailer? Not specifically for a jon boat but...

You must be retired. I am and starting work at 10 am is my usual routine.
"The best thing about being retired is getting up when you're done sleeping" ... 😎😉

It's very helpful info that the bottom of your transom is 26 inches above the ground. That is the kind of info I'm looking for.
Regarding the skeg of the outboard being 11 inches above ground in...

If I can find a small used trailer, I suspect it will come with bunks but no rollers.

My primary concern is what is the typical height of the boat's bottom off the ground. Reason is if the flat...

I'm going to start looking for a used trailer for the flat bottom jon boat that I'm building. When a boat is sitting on its trailer, what is the typical height that the bottom is above the ground...

I bought sande marine ply for my boat so the bench seat tops are 1/2" ply. Will carefully apply primer and paint to the end grain and see what happens. Will probably be fine since the boat will...

Cure time delay will negate that move for me. Thanks.

I've decided to skip epoxy on the topside and just go with primer and paint. Thanks for the help.

Thanks for taking the time to post the West narrative. OK, what you said in bold above and along with what Todd said, I'll skip epoxying stuff on the topside and just go with primer and paint. Will...

If I apply coats of epoxy when the previous coat is tacky, will blush be a problem? Or does amine blush only occur when the epoxy fully cures?
What's your recommendation for the number of days to...

As a novice boat builder, I didn't know the correct term. Thanks for the education as I do want to use correct terms when discussing boat issues.
Foredeck it is from now on. Thanks.

I'll do that along the lines of my response to Todd's post. Three coats of epoxy on the bench seat tops, primer and 3 coats of topside paint. Thanks for your input.

Thanks for the info and picture examples. Since the Gougeon Brothers are OK with putting epoxy without cloth on topside surfaces, I think I'll put 3 coats of epoxy on the bench seat tops first (most...
