not always phrag your bilge and stringers were different and needed a bit of help standing up along the way. for purely flat work wet on wet all the way (usually)

actually I would do them all at the same time wet on wet, no need to wait for it to tack up. Its easier to wet them out if you do them this
way. I prefer to do them as rapidly as possible and fairly wet then balance out the excess after its all laid up. You'll notice that the mat side is the toughest to saturate and unfortunately the side you lay down. if you over saturate the layers as you go it will help wet the bottom side of the subsequent layers and give you a head start on the final balance . . . . . not sure if any of this sense lol :D

Another thanks, called US Composites and they explained it at length to me. They say coat the wood and wait for it to get tacky (about an hour). Once tacky lay laminate and start soaking with roller. Wait for it to tack up again a reapply, each time make sure it goes clear

Yeah you got to move fast, are you using polyester resin? You shouldn't have any problems using polyester it is really viscous (more so than the vinylester i used) and wets out really nice and quick. Mix 1000 grams of resin at a time and use a roller and a bucket big enough to dip the whole roller into. If the laminate starts to get away from you like it did the first time just do whatever you have to in order to wet it out, I was sort of pouring resin at the top of the laminate and having it trickle down. If you put too much resin in one area you can push it around with the roller and have other areas wet soak it up. If you end up with a pool of resin at the bottom of your bilge push it up with transom with the roller and have dry areas suck it up. You do want a balanced laminate like dave says but never let it get away from you its not worth it :)

For me doing the stringers with pieces that went all the way up and over was the hardest part especially with vinylester because it was much thicker. I almost had one get away from me and what a disaster that would have been.

It helps to have someone outside the boat mixing resin ( i never had that lol but it would have been nice) because jumping in and out of the boat 50 times is so annoying. I ended up putting apiece of plywood accross the boat as a table infront of the engine bay and lining up my resin and MEKP premeasured out ready to go if i needed more.

You can do up to 3 layers or so all at once no need to wait an hour in between. You will get a better bond most likely the more wet on wet you do.

You should go on youtube and look up friscojarrettes sea ray rebuild he has a lot of good videos showing layups
