Just found a fiberglass tape product. Anyone have experience with that? I'm supposing that I could put the tape around the edges of the scoop, seal the tape with epoxy resin, sand and paint. It come in various widths, from 2 to 6 " or so.

Read very carefully the directions that come with whatever brand you buy. It is critical to get the mix just right or you might just end up with a big goopy mess or a very hot solid lump in your cup. Don't do it by eye, use mixing cups or some similar device to get consistent drying and hardness times. I use West System resins/hardeners and the pumps that they supply. The pumps give the exact mix ratio each and every batch.

I use glass tape all the time for repairs. Don't go too heavy on the thickness of the tape or the resin. Thiner is better for molding to curves and odd ball shapes.

I'll bet he's looking at the vent. Andy, I'll keep your part in mind if my fix doesn't work. My scoop is not in terrible condition, so I'm going to try a repair first. Thanks!

A word or so to help you.

Patching, won't last very long, as the plastic will continue to crumble.

You can try coating both sides completely, so that the old plastic is totally covered with the fiberglass.

For your last coat on the vent surface that you will be looking at, you perhaps should also consider a final coat of "gelcoat" with the colonial white (ivory) color.

All you can do, is give it a shot.

Andy

Andy, good point about that plastic-it's so brittle. Really appreciate your advice

Epoxy resin mess

It will be a lot cheaper than buying and shipping on a new one.
I ended up using the west system epoxy and fiberglass cloth. It was great on my plastic wheel well covers, but on my reefer scoop, I messed up the measurements and it won't cure. I have tried to remove it, but it just made a bigger mess. The holes are repaired and hardened, but the middle is sticky. I'm thinking of sanding down what I can and applying metallic contact paper to cover the sticky spots. Is there a flammability problem with this idea?

Thumbs up warm it...

Sara,

A heat lamp might help, if it has cured in one spot,(same batch?), and not another.

Sara,

The epoxy resin is NOT flammable, polyester is.
You could cover the repair if you like, it may still cure if given enough time.

To all who have gone or will go the non cured epoxy resin path, I can attest that there is only one solution. If it doesn't cure in 24 hours it will NEVER cure. I waited 3 months and did everything I could to get it to cure. The only "cure" is to scrape the gunk off with acetone or other solvent. I mixed a new batch, applied it and it cured in a day. Yay! Solid, but not very pretty scoop. Still need to sand and paint.

Sorry, I didn't see this earlier. Generally, if epoxy won't cure, the best answer is another thin coat in the right proportions. Don't know why it works, but it doese seem to result in curing the whole mess.

In your case, sarasafari, if yoiu have a rough surface, and you plan to paint it, one thing you can try is a topcoat mixed with a lot of wood dust. The wood dust is more sandable than the cured epoxy resin, and should make it easier to sand to a smooth surface for painting.

Thanks for your response, Jamespio. I did remove the old and put a correctly portioned amount on, and it cured perfectly. I don't know if I got the old stuff off, or the new coat cured it. Thanks for letting me know about the wood dust. It is pretty rough because I had also painted over the uncured scoop, hoping that would cure it. WRONG. I was thinking of just spraying a textured paint on, so it looks like granite, or something. I am out of the West products and they are so expensive that I don't want any more epoxy on it.
