Holts LOYCAT13 Cataloy Knifing Putty Tube, 100 g (Pack of 2)

I used this excellent product for scratch repairs on a plastic car bumper. Application needs to be made quickly and thinly as it dries rapidly and adheres to the surface very well, but very easy to sand to a smooth finish to accept the finishing paints. I am impressed and such a low price too!

I've used it on the car easy to use the wife has been using it on the indoor paintwork with Great success

Easy to use and easy to sand. Definitely would recommend.

This filler is brilliant! I use it to join 3D printed section of RC model U Boat hulls. It sets quickly and is a doddle to sand by hand. The photo shows a 67in long U-boat I 3D printed in 12 sections. This filled the joints and sanded so smooth. Gone through 5 tubes on various projects. No hardener required so no mixing or worry about the right ratios. Just spread it on, wait a short while, sand and paint! Good price too. Just bought more to keep as spare.

Really hard to rub down

Not the best instructions. Applied first coat & sanded, noticed I had sanded in the same direction of the scratches also applied in the same direction so have now applied at about 45 degree angle, will do the same with the sanding, softly. bought the "Wet and Dry Sandpaper 1000 1200 1500 2000 2500 3000 5000 7000 10000" , started with the finest went to the 1200, then reapplied the filler. I am allowing 24 hrs before doing any sanding.Most important not to fill large scratches in line, same as sanding.Yes it works well, bonding to the Zafira paint, primer very well. The Zafira (09) has great paint work, on the body, pity they did not do the same with the under body. It is not bad for 09 plate but could have been better.Watch this space

Great product, works a treat.

Claggy, thick paste but there’s a trick… Dilute with pure acetone and spead onto FDM prints that have prominent layer lines. Dries very quickly when diluted this way. Wet sand with fine grade papers for a super smooth finish.
