I'm not sure what "coaming on a lorry" is, but I have experience removing paint with a needle scaler. If working on iron or steel, the thicker the metal the better it works, thinner materials it just does not seem to work as well. Frozen paint shatters better than warm paint. Use eye protection, respirator, hearing protection, after a few hours you will get in the zoneHAs anyone used a needle scaler on removing thick paint? The ones I am looking at are air operated and I want to clean up the 20 layers of old paint off the coaming on Lorry and then it will also clean up the rusty bits too.
Correct Scotty, use a lot of air. Bloody noisy too.Hello Cobba
I wouldn't be without one but as mentioned, good for very hard or loose paint or rusty stuff. I don't know how it'll go on Lorry's rails. You could do a test and see what happens if you bash the sides with a small ball pein hammer. If the paint comes off easy in chunks then the scaler will work. A word of warning though, they need a good supply of air. a 12 or 15 cfm compressor will be continuously working to try (and failing) to keep up with the scaler if you get fair dinkum with the scaler.
Personally I'd be getting some sand blasting quotes.
They are great for weld prep and scale removal but can be a bit hit and miss with paint.HAs anyone used a needle scaler on removing thick paint?
