new to forum, resto, and safe-t-cap

i am looking at purchasing some frame repair kits for my 1969 plymouth barracuda notchback to begin my project. full on resto isn't important to me, i prefer a pro-touring approach (as much as my budget will allow for now).

my question is about "capping". anybody have experience with this company, auto rust technicians (safe t cap)? repair is not likely, replace would be ideal, but maybe approachable. the kits i looked up were the torsion mount, set and the front subframe, rear section set. solid metal is available to weld too on my car. these repairs need to be done before i can drive "muffin" and get to the stuff i enjoy. the repairs will be handled by someone more capable than i as this is my first personal project.
