Coating a JW foamie with goop to add weight?
How do I coat my JW with goop to add weight for DSing? How and what do I use to thin the goop? I believe I am suppose to thin it enough to roll it on with a paint roller and put like eight or nine coats on? I would greatly appreciate any help on the subject. Thanks

I've built a couple JW 60's.
You need to thin the Goop in a glass jar, like a tall peanut butter jar, with Toluene or Xylene. Squirt a whole tube of goop in the jar and mix in toluene till you get a syrup consistency. Mix in some (enamel is what I use) pant to tint the thinned goop. I'd use a paint brush and cut the handle so it fits inside the jar with the lid on so you can resuse it.
Paint a coat on the bare EPP and let dry. Should dry in 15 minutes. Then use Bi-directional Fiberglass enforced tape from home depot/lowes/etc, lay it on smooth then shrink it with a covering iron. Then clean the tape with paper towels or a rag with toluene or alcohol, then lay another layer of tape and shrink.
Also I hang the fuse nose down from the wing cut out when drying. Each coat should dry in 15 minutes, so you can put multiple coats on in an hour.
Paint on a couple layers of Thinned goop, lay on a couple layers of tape. Repeat till you run out of tape. Then brush on as many layers as you want of the tinted thinned goop. Add more coats on the nose cause you'll need nose weight.
If you get a blob or run you can rub it smooth with the brush or a rag wet with toluene.
Here is a summary of my JW
The first link has all the best ideas for a go fast JW. One thing you should consider is to fix the outer 2 inches of the TE.
