## Description

ProSeal 80046 Silicone Instant Gasket, Black : desertcart.co.uk: DIY & Tools

Review: Great reusable "instant gasket" - Works like sealant, but is easily removed and reaffixed in the future, acting more like a traditional rubber gasket. Used to seal around some badly fitting lights on a vehicle which was causing water ingress, sealed perfectly with very little used, since found all sort of other applications for this around the home. Great product.

## Questions & Answers

**Q: I put this on my brow thinking it was draw on eye brow i now have no eye brows**
A: use eye brow pencil ..............not pro seal ......good luck

**Q: Can I use this to fix my oven door glass back on to its metal frame**
A: I would tend to say no - whilst this does withstand heat, it is a gasket replacement sealant, not an adhesive.  So if the door glass was held in mechanically with fixings, this could be used to bed it upon (seal it in place).  This is product is designed to be trapped and held between two mating surfaces.

**Q: would this work to seal my fridge door seal please?**
A: I am not sure what your question means but please be aware that this is a gasket sealer meaning that it sticks 2 surfaces together permanently.  If you need to stick the existing door seal to the door it might work, but be aware that it is black and would look very unsightly.  I think you would be better off buying a clear silicone sealant.

**Q: Is it waterproof for outdoor use?**
A: This product has been designed for use on oil pans rear end housings, water pumps, valve covers, thermostat housings, electrical connections and wires. Seals windshields, sunroofs, doors, lights and hose connections. Yes it is suitable for outdoor equipment.

### ⭐⭐⭐⭐ Glued well.. bottom of tube burst
*by A***R on 16 April 2022*

It works well. The bottom of the tube burst whilst squeezing (we read the reviews so knew to be extra careful squeezing, still didn't help). Luckily only needed to to glue 1 thing. Scraped glue out from the bottom. It's glued well with no issues so far. Easy to use. Just what we needed.
