Will fiberglass stick to body filler?

The fiberglass resin can cure to a very smooth finish that paint may not stick to permanently. When you sand it you put tiny scratches in the surface. The body filler will penetrate these tiny scratches and adhere well.

Re: Epoxy fiberglass over polyester filler? You will be fine. Epoxy will bond to quite a number of surfaces “including” polyester resins. Just rough up the surface so you will get the maximum mechanical bond from your epoxy.

Fiberglass Bondo is waterproof, extremely strong and Can be used for virtually any fiberglass panel. As an initial matter, it must be recognized that there is Bondo for metal and Bondo for fiberglass. Ensure that the Bondo for fiberglass is used.

The cured resin is compatible with nearly any paint system including gel coat and marine paint. Along with its strength, Bondo® Fiberglass Resin is also simple to use. It is easily mixed using the included Bondo® Liquid Hardener, designed specifically for use with Bondo® fillers and resins.

Sure it will work fine. It looks like in a couple of posts “epoxy” and “resin” are used for the same material. Fiberglass resin and Epoxy are two different animals. “Fiberglass resin” won’t stick to epoxy well, but “epoxy” (such as West or System Three) will work over the resin.

Bondo has a polyester resin base so ya… Polyester fiberglass resin (or gel-coat) will bond fine.

Mix the Bondo® All Purpose Fiberglass Resin in a paper cup with the Bondo® Fiberglass Resin Hardener. For small applications use 10 drops of hardener per ounce of resin. Working time will be 10 to 12 minutes. For larger applications, use half of the fiberglass resin hardener supplied, to half of the resin container.

Fiberglass repairs should be made with vinylester. If you are needing a high strength filler there is only one vinylester based structural filler on the market, and that is 3M High Strength Repair Filler.

46 Epoxy primer must dry for one hour and all metal work must be completed before starting the body filler process. Applying body filler over epoxy primer provides maximum corrosion protection for the metal. Apply filler within seven days of applying epoxy primer to maximize adhesion.

Well No, it won’t harden. It might eventually go dry and crusty, but that depends on the resin, and it would be super brittle in that state anyway.

Will fiberglass resin stick to plastic? The answer is simple and oh, it’s a yes! To say it straight away; Yes, fiberglass resin will easily bond with plastic And is commonly used as an adhesive for repairs and reinforcement.

The epoxy product that I have used (Abatron) is worth the extra if for no other reason that it sands more like the wood, whereas Bondo is much harder than the wood and will tend to stand proud of the surrounding areas if you’re not careful when sanding.

Epoxy is a great adhesive

One reason that an epoxy product such as WEST SYSTEM® Epoxy is so useful for fibreglass boat repairs is that it’s an incredibly effective adhesive. It creates a resilient bond to fibreglass, cured polyester laminates, wood and metals – even when you only use a thin film.

Gelcoat is a different type of resin. Usually an iso resin which has different properties such as UV resistant, more moisture resistant etc. It’s true that you can add colour pigment to your gelcoat but the purpose of gelcoat is to be the outer protection layer because of its superior properties.

Incorrect Surface Preparation – Gelcoat will only adhere to Fiberglass, previously cured gelcoat, or polyester resin. Do not apply gelcoat to any paint or protective coating because it will not adhere. Existing paint will have to be removed. In order to prepare the surface correctly, it must be sanded.

Natural Alternatives to Fiberglass Cloth

• Bamboo cloth.
• Hemp cloth.
• Flax cloth.
• Timber veneers.
• Basalt cloth.

Before sanding, let the fiberglass sit out in the sun for 2 to 7 days To cure the gelcoat. This process releases any air pockets from the gelcoat that would cause problems when sanding and painting.

Primer for bottom paint is not necessary. However, if you use Tuff Stuff marine epoxy primer on the bare fiberglass, it will provide protection against blisters and any moisture. It will also improve adhesion to the hull. Tuff Stuff marine epoxy primer will last for many years.

We often get asked about metal body fillers or reinforced fillers and what they are. These fillers are Incredibly strong But do have their place in the body shop.
