Experience with "self-fusing" silicone tape (e.g., Rescue, Help, Tommy)?

I’m considering using a product of this type to repair the windshield washer reservoir on my car*, and I’m curious if anyone has any experience with it.

Is it actually adhesive (like duct tape) or does it only stick to itself?

The specs for Rescue tape say it withstands temps up to 500[sup]o[/sup]F. Would that suffice for under the hood of a 1998 Toyota Corolla?

  • which has developed a strange hole along its top edge, which I think is allowing the washer fluid to evaporate or possibly simply slosh out.

The tape sticks to itself and likely won’t work for your application. Look for two part putty epoxy meant to repair radiators or fuel tanks, it will likely do the job for you.

Out of curiosity, I went to www.rockauto.com and found a replacement windsheild washer reservoir listed for $31.79.

I don’t think the tape will stop the leak. I also think the tape will have a difficult time sticking strongly to the polyethylene the tank is made of.

I just read the * in the original post.

The strange hole along the outside top edge of the tank is common. It is UV damage caused by the sun peeking through the gap between the hood and the fender. This exact elongated hole happened to my Corolla and also to my wife’s Maxima. When I received a new one from rockauto for the Maxima, I washed the outside with soap and water, masked off the bottom of the reservior, and painted the top with gloss white Krylon Fusion spray paint. Krylon Fusion is designed to adhere to plastics.

The gloss white spray paint will hopefully prevent the UV damage from occuring again, or at least delay the photo degradation of the plastic.

Thanks, toofs. Yeah, that price is about what I’ve been finding for a replacement reservoir, too. I was hoping to save a significant percentage with the tape, but it’s sounding unlikely.

Thanks for the suggestion on the modification to what looks likely to be my new reservoir!
