Resins, activators, and/or catalysts used in the repair of plastics, including fiberglass, may be flammable. Do not use near heat, sparks, or open flames. Use only with adequate ventilation to avoid fumes. Wear protective gloves to avoid contact with the skin. Avoid prolonged breathing of the vapor or spray mist. Do not take internally. Keep out of reach of children. Before smoking, eating, and after using, cleanse hands thoroughly. In the event of contact with the skin, flush the skin with plenty of water. For eyes, get medical attention.Read, understand, and follow both the instructions for use and the warnings which are packaged with, or printed on, the repair material containers for the specific repair product you are using.
Mix two part filler and cream hardener together following container directions to make the filler.Note: The preferred filler for blister is fibral.
Fill void with the filler using a firm but flexible putty spreader slightly larger than the defect.When applying the repair material, use an up and down motion then left to right to reduce trapped air.
Cover the repaired area with a piece of masking tape and using the palm of your hand, run back and forth over the repair to force out any trapped air.
Remove excess material from the part that was forced out around the tape. Let filled repair cool to room temperature.
Sand the repaired area until the excess repair material is removed.Note: If pinholes are still present after repair is complete, the area must be filled again.
Use a safety nozzle to blow all dust off the part and spot prime repaired area. After spot prime dries, scuff all spot primed areas.
Paint the repaired area. Refer to section "Painting the Repair" in this publication.Painting the Repair
A rough surface may be applied to the repair material. A rough surface will allow paint to stick to the repair material. Allow the material to remain unpainted for at least 4 hours. The materials will oxidize for better adhesion by the paint.
Avoid prolonged skin contact with isopropyl alcohol. Avoid breathing the vapors in enclosed areas without adequate ventilation and do not smoke.Isopropyl alcohol is flammable. Do not use near open flame, welding operations, or around heated surfaces exceeding 482°C (900°F).
Do not use petroleum-based solvents to clean the material. Petroleum-based solvents will cause deterioration of the material.
Clean the entire area of the repair. Also clean the surrounding area around the repair.Use soap and water to clean the areas. You can also use isopropyl alcohol to clean the surfaces.
Allow the cleaned areas to dry.
Cover any area which will not be painted.
Before you paint the repaired area, wipe the area with a new tack cloth. The cloth will remove any foreign material which may be present on the surfaces.
Paint and products used in painting may be flammable and hazardous. Read, understand, and follow instructions for use on the container. Wear NIOSH/MSHA certified respiratory protection.
Prime the repaired areas with a suitable epoxy primer that is compatible with urethane paints.Note: Primer is not used when touch-up paint is
