I had a broken plastic engine cover on a Caterpillar mini digger. All local workshops demanded exorbitant sums for this. Something had to be done as this part helped keep dirt and debris out of the engine. So I decided to try this. Let me say there is a learning curve here. Practice on unnecessary material before showing it. I picked up the pieces and put them together like a puzzle. Then I started using it bit by bit until I was done. It's not the most aesthetically pleasing renovation ever done, but it's reliable and functional. I'm glad I found this. This saved me a lot of money and got my car running again.
