Really good for doing exactly what it says. Just the right consistency.

I bought this to repair cracks in the gel coat of my car. It’s very important to realise that you will not get a cosmetic repair with this. I have no idea whether the cracks fill in for a structural repair but this will not hide the cracks. In fact you have to polish off all the excess to stop it looking awful. Actually..... the cracks end up looking worse because you have the scrape them out with a pin that makes them bigger!! Maybe it’s fine if the cosmetics are not important but hopeless for cars. The photo is AFTER the repair!!

ok

I was dubious about this product given the price but I have a 40 year old boat with lots of crazing (Fine scratch lines) Make sure the area to be treated is clean, I used a kitchen bleach product (HD) and scrubbed with a nail brush before pressure washing. Its a bit fiddly to use but I found the result "magic" as described. The temperature needs to be warm, ideally 20*c for it to cure but I also did an area and used a hair drier which worked just as well. The secret is to just do small areas at a time and as long as the cracks are no more than 2mm it works fine, just bought 2 more tubes!

Very runny did not match the colour that's well and did not cover very good

Just used it on my water feature easy to use and application is good..

Great for hairline cracks, but you do need to work within the temperature range stated, if it is colder, you need to use a hot-air gun to cure it.

Despite following instructions and repeating the process several times this did not hide hairline cracks to my tiles at all. Very disappointed and expectations were not met.

Super easy to use! Worked like a charm!!!!!!!!!!!

We had some hairline cracks in a custom-sized terazzo base that was likely installed in the late 60's when the house was built. There had been a previous repair we scraped off that had just sat on top of the cracks and had gotten discolored and dirty. This product was thin enough to actually sink into the cracks so there's no raised edge. The repair is visible, but restored usability at a tiny fraction of what it would have cost to have it professionally repaired or replaced. Plus, there's no discoloration so far, even after a little more than 1 year of regularly using the shower. Update in 2026: It's now been about 3 years and the repair is still going strong with no signs of wear or deterioration

Parfait

Excellent product for repair

Worked well. Needed multiple applications to fill the gel coat crack but the color match was very close and it buffed well with my 3M Imperial Hand Glaze.
