Mine had 4 of those strips laid in the outer strakes and glassed over...When I ground them out, I just refilled them with a thick, hairy peanut butter then glassed over them with CSM and 1708...
Probably cost more in materials than filling with wood then glassing, but I figured they will never again turn to mulch this way...
Just a few questions for when I get some time on the boat.
(1) Should I coat the 1/4"x 2" wood strips I'll be replacing in the hull with resin before I glass them in ?
Any wood that is going to be coated with glass/cloth, should be pre-soaked with resin to prevent the first layer of glass/cloth from having the resin sucked out of it and creating a dry layer...similar to pouring concrete in a mold, you want to pre-wet the mold, so the water content in the concrete doesn't get suck into a dry mold...
(2)Do you have to ruff and scuff all layers of glass if allowed to set up ( as in next day ) before laying on more layers of glass?
I use a method that was shown to me by a Corvette Repair Shop Owner that I worked for in my youth, I wipe the area in question down with Acetone, if it becomes sticky/tacky, you are good to go, if it doesn't, you should ruff-n-scuff...you see the theory behind it is that if the surface remains tacky after wiping w/acetone, there is enough open surface [on a molecular level] for a good mechanical bond to the previous lay ups...remember, unless you do all of your lay ups of cloth/resin while everything is still somewhat soft and wet, which is the ideal "Chemical Bond", after just a few hours of curing time, you lose that window and it becomes a mechanical bond, no matter how much you grind, I would NOT necessarily trust this method after more than a couple or three days, and would definitely do a light ruff-n-scuff of the surface prior to re-laminating...and see my disclaimer in the next answer...
(3) How does the wax added to the last layup aid in sanding? Wouldn't it clog up your disc or paper?
Personally, the only place I would ever consider using waxed resin, or PVA, or whatever...is for the very last layer of finishing gel coat, if that is what your finish is going to be...otherwise, any final layers of glass/resin will probably be covered with something other than gel and will be fully cured in a matter of days, PLUS the fact that unless it is the final layer, and you have to sand, you avoid having the sandpaper clogging problem...Disclaimer; This is my opinion from several years of practical working experience with this stuff and with guys who have been doing it for bookoo years, and is in no way to be accepted as fact, the true experts on the subject are now welcome to shoot me down in flames...:laser::brick:
Thanks, I hope I don't sound too dumb!Never!
This is a learning experience.That is what this site is all about...
