Here's how I recommend that you install your stringers. I would use the 404 or 435 Poly resin and 1.5 oz CSM mat and 1708 Biax Cloth. Start with 5 gallons of resin and 15 yds of mat and 15 yds of 1708.
Coat the stringers in Resin and apply the CSM making sure to wrap the edges. When they are dry, Lay down a bead of PL Premium Adhesive on the bottom edges and let it set for a couple of hours so it will firm up a bit. When it is firm but still a bit squishy, install the stringer and tab it to the hull using 3 inch wide by 12" long pieces of the 1.5oz mat. Mix your resin HOT so it will set FAST. This will get the stringers, IN PLACE and vertical. (NOTE: Make sure you have a way to brace them and keep them 90 degees and in place). When the tabs dry, mix up the Peanut Butter(Thickened resin) and fillet in the stringers using a Large Plastic Spoon. Wait till the NEXT DAY and then start laying the 1708 over the stringers. The first layer of 1708 should extend out on the hull approx. 4-5 inches and the 2nd 8-10 inches. Try REAL hard not to get air bubbles in the cloth. Use your hands and the stick pins to hold it all in place. A 6" Plastic putty knife works well to help smooth and spread. Just don't STARVE the cloth of resin.

Good CATCH!! Mistake in Drawing!!!! The Stringers Are ONLY encased in CSM Before Bedding in PL. The 1708 Is ONLY on the OUTside and Attached to the HULL. I will correct the drawing for future Posts. Thanks for the Heads Up!!!
Yes, you should always Precoat your wood before laying mat. And it does sound like your resin mix was WAY off. What % ratio did you use? You need to scrape off all the bad goopy stuff, Clean it REALLY well with ACETONE and start over.
Well the mekp instructions said for temps over 90 degrees decrease mixture by 50% so it was about 630pm and about 95 f outside I mixed it up at 50% reduction poured one quart of resin then mixed in 1/8 oz of mekp instead of 1/4 oz....... so gonna give her another run tonite and i will mix it up hot!!!!!!! do not want to have to do it a third time thanks wood!!
Like my drawing shows, you're gunna be mixing some thickened resin when you set your stringers so use it to fill the gouges then. Sounds like your making progress. Uhhmmmmm where's those pics to prove it!!!![/QU
hahaha well i thought u might mention that pics maybe tomorrow!!![]()
What does PL stand for? I'm trying to learn this so I can start on mine. Have to ask.
