Пользуюсь инструкцией из книжки братьев Gougeon'ов по подготовке поверхности -

Epoxy surfaces that are still tacky may be bonded to or coated with epoxy without washing or sanding. Before applying coatings other than epoxy (paints, bottom paints, varnishes, gelcoats, etc.), allow epoxy surfaces to cure fully, then wash and sand.

Hardwoods—
Sand with 80-grit paper.

Teak/oily woods—
Wipe with acetone 15 minutes before coating. Solvent removes the oil at the surface and allows epoxy to penetrate. Be sure solvent has evaporated before coating.

Porous woods—
No special preparation needed. If surface is burnished, possibly by dull planer or saw blades, sand with 80-grit paper to open pores. Remove dust.

Steel, lead—
Remove contamination, sand or grind to bright metal, coat with epoxy, and then (wet) sand freshly applied epoxy into surface. Re-coat or bond to the surface after first coat gels.

Aluminum—
Remove contamination, sand to a bright finish, and prepare with 860 Aluminum Etch Kit before oxidation occurs. Follow kit directions.
Polyester (fiberglass)—Clean contamination with a silicone and wax remover such as DuPont Prep-Sol™ 3919$. Sand with 80-grit paper to a dull finish.

Plastic—
Adhesion varies. If a plastic is impervious to solvents such as acetone, epoxy generally will not bond to it. Soft, flexible plastics such as polyethylene, polypropylene, nylon, and Plexiglas fall into this category. Hard, rigid plastics such as PVC, ABS, polycarbonate, and styrene provide better adhesion with good surface preparation and adequate bonding area. After sanding, flame oxidizing (by quickly passing the flame of a propane torch over the surface without melting the plastic) can improve bonding in some plastics.

И чем хороша Эпиталовская эпоксидка 320 + 45 отвердитель, то что пресловутый amine blush практически отсутствует.

по поводу ширины -- хехехе, представьте что будете с креном идти и ногами опираться о противоположное -- станет хотя бы морально удобнее ;)

Стало удобней но страшней :))), что то не готов я морально (пока) к таким кренам катамарана - шобы на одном поплавке ходить надо экспу сначала нехило прокачать - как минимум до 20 уровня :))))))
