Inside hull paint/sealer

Daryn,
There are several options for cleaning up the bilge. Some have gone with Bilgekote made by Interlux. Some have used epoxy garage floor coatings and then the one I like is to simply use epoxy tints to color epoxy resin.

You mention "seal" the fiberglass. Fill us in on your concern.

Daryn,
How about posting some pictures of the boat? We'd love to see what you have. What engine is in it?

Pics will load easy from computer. No so from phone

APPLICATION AND USE
Preparation
BARE FIBERGLASS: In Good Condition Begin by scrubbing well using soap and water and a stiff brush. Rinse with fresh water and allow to dry. Degrease by wiping with a rag soaked in Fiberglass Solvent Wash 202. Sand with 180 grade (grit) paper. Remove sanding residue. In Poor Condition Clean as above. Sand with 80 grade (grit) paper. Apply Interlux Pre-Kote Primer INT-4279Q.
BARE WOOD: Sand surface, wipe clean. Apply White Undercoater Pre-Kote 4279. Sand surface, wipe clean.
BARE METAL: Sandblast or grind, remove sanding residue. Immediately apply Viny-Lux Primewash 353/354 thinned 25% with Viny-Lux Solvent 355. Allow to dry for 1-24 hours. Apply one coat of Epoxy Barrier-Kote 404/414.
CLEAR EPOXY: Begin by scrubbing well using soap and water and a stiff brush. Rinse with fresh water and allow to dry. Degrease by wiping with a rag soaked in Fiberglass Solvent Wash 202. Sand with 80 grade (grit) paper. Remove sanding residue. Apply one coat of Epoxy Barrier-Kote 404/414.
PREVIOUSLY PAINTED SURFACES: The surface must be clean and dry. Sand using 180-220 grade (grit) paper. Remove sanding residue.
Method Apply 2-3 coats of Bilgekote following the proper dry times. Sand between coats using 220-320 grade (grit) paper. Remove sanding residue with a rag dampened with Brushing Liquid 333. Bilgekote may be applied by roller and brush using the roll and tip method.
Hints
Thinner Brush - Brushing Liquid 333. Spray - Special Thinner 216.
Thinning Thin if necessary with Brushing Liquid 333 to improve brushing characteristics. For spray application use Special Thinner 216. Thin no more than 10%.
Cleaner Bare Fiberglass - Fiberglass Solvent Wash 202. Epoxy - Fiberglass Solvent Wash 202.
Ventilation and Humidity Control It is best to paint on warm, dry mornings. Cold weather retards the drying and humidity can spoil the gloss.
Airless Spray Pressure: 170 bar/2500 psi. Tip Size: 0.33-0.41 mm/13-16 thou.
Conventional Spray Pressure Pot: Pressure: 3.44-4.47 bar/50-65 psi (gun pressure); 8-10 psi (pot pressure). Tip Size: 0.89-1.4 mm/35-50 thou. Siphon Cup: Pressure: 3.44-4.47 bar/50-65 psi - gun pressure. Tip Size: 1.5-1.8 mm/60-70 thou.
Other Spray pressures listed are recommendations only. The applicator may use any settings which yield the best results for the individual spraying technique and current weather conditions. Bilgekote is best applied in thin coats.
Some Important Points Do not apply heavy coats as this will affect dry through. Failure to follow proper dry times carefully will cause improper drying, wrinkling and loss of adhesion. Product temperature should be minimum 10 deg C/50 deg F and maximum 29 deg C/85 deg F. Ambient temperature should be minimum 10 deg C/50 deg F and maximum 35 deg C/95 deg F. Substrate temperature should be minimum 10 deg C/50 deg F and maximum 29 deg C/85 deg F.
Compatibility/Substrates Surface must be dry and clean, and free from grease, detaching paint etc. Be sure to use Epoxy Barrier-Kote 404/414 over clear epoxy to prevent blush from affecting drying and adhesion of Bilgekote.
Number of Coats 2-3 minimum
Coverage (Theoretical) - 300 (sq ft/Gal) by brush, 240 (sq ft/Gal) by spray
Recommended DFT 2.0 mils dry
Application Methods Brush, Roller, Airless Spray, Conventional Spray - Pressure Pot or Siphon Cup
