body work tools question

Hey guys I was wondering if anyone can give me some advice on these body blocks I am thinking of purchasing. I want to paint my 68 Cuda fastback john deere blitz black (untill I have the time and funds to do it right) but for now the body needs a bit of tlc, couple dents and dings that need to get massaged. Would this be a good purchase for the work I will be doing? Thanks for any infoView attachment 1715027814
