There are a lot of different ways to repair a damaged catcher and this is the first catcher that I have plastic welded with a soldering iron and some plastic from a plastic Victa discharge flap that was used for plastic welding rod.
I don't recommend this method unless you have a difficult to find catcher and you want the catcher to look original when repaired.
Some images of the catcher may help others to decide which way they wish to restore a catcher as I've never seen images of a plastic welded catcher before.
I used a little spray putty from a spray can and then used some duplicolor black vinyl and fabric dye from a spray can on top of the spray putty primer and the black vinyl dye makes the catcher look new again.
I've used similar combinations of paints on trail bike plastics before and it lasted well also didn't need to buy the paint as I had some left over from other projects.
This black is about the best I've seen to match a black catcher ,I have a Victa twin catcher that needs a lot of welding but it's orange so if I get around to fixing that one ,I'm not sure if I could find the correct colour or if I just use a red or paint the twin catcher black.
Pic below shows the catcher sanded and a little black but no spray putty ,I decided to use a thin coat of spray putty to make it look original like new as the catcher also had a few scratches other than the repaired section but I haven't made the complete catcher look brand new just mostly the top and back sections that you see the most.
Yes the catcher came out good without any distortions on the plastic Norm, with a little help with some Neodymium Magnets to hold all the plastic together when welding, the welding process was a little slow because I used a 40 Watt soldering iron.
I do remember AVB previously recommended an adjustable temperature iron ,which would have been better. and they aren't expensive.
