make your UL-1 rock solid

[Steven Vaccaro]

I've been trying to get the NHP version of this product for several months now. It was sold in smaller sizes. Seems NHP is out of bussiness or doesnt want to return calls.

Do you guys think that adding this foam would help with the side fin issue at all?

That's the foam I'm using. Great stuff! $30 delivered for the two quarts is a bargain! Look around the net, their price is FAR below what most people want for this stuff. The two quarts (1/2 gallon) will last a LONG time because a very small amount the stuff expands tremendously.

For my UL-1, I drilled holes in 5 places, one in the front of the compartment and two on each side. I used .85 oz by weight of each component and did the pour in each hole.

A tip...when the foam comes out of the hole it will get on the surface inside the radio compartment. Use some clear packing tape to cover the hole and then cut the hole out prior to pouring. When the material is fully set up and hardened, cut off the excess with a razor saw and then pull off the tape. It will take any residue with it!

BTW, you want the 2lb. density variety!

This is the stuff I ordered from US Composites

2 LB Density Urethane Foam
(U.S. Coast Guard Compliant Marine Foam)

FOAM-0204 4 LB Kit 2 Cubic Feet $20.50

Common Applications: Our 2LB density marine foam is recommended for void filling in nonstructural applications. This product can be poured underneath decks and inside cavities where a lightweight flotation foam is needed to provide buoyancy. This foam has been tested in accordance with U.S. Coast Guard Regulation # 33 CFR 183.114 . This foam is approximately 95-98% closed cell which resists absorbing water, however continuous water submersion can eventually lead to loss of buoyancy over a period of years. We recommend this product strictly for flotation applications. If looking for a liquid foam for sculpting or casting we recommend using at minimum our 3LB or 4LB density.
