The Timeline of the Evolution of Thermalweld
Thermalweld is the final result of years of lab work, field experimentation, and real-world experience. The below timeline will reflect its evolution.
1995
Thermalweld was invented by chemist Robert “Bob” Hooper.
1997
Bob Hooper establishes a mobile head gasket repair service, which he branded Thermalweld, in his local area while learning how to diagnose coolant system issues.
2004
RXAuto contracts with Thermalweld to provide product and technical support for its label Thermagasket. Under the said label, Mr. Hooper authorized, trained, and supported nearly 100 mobile technicians nationwide, many of which are operating to this day.
2010
The relationship with RXAuto was severed by Mr. Hooper. In those years, nearly 20,000 vehicles were diagnosed over the phone and repaired with more than an 95% success rate. Sales reached over $70,000 per month.
2011
Mr. Hooper entered into a relationship to provide technical support for Steel Seal Ltd, a chemical solution provider from the UK, selling the product over the internet as well as to various retailers in Europe.
Mr. Hooper provided third-party diagnostic analysis to help solve the failures that the Steel Seal formula created. During that time, Thermalweld was improved and relabeled as “Steel Seal Elite” and used to repair head gaskets, including the Cadillac Northstar engine.
In addition, Robert invented a “bleeder apparatus”. The treatment and assembly has been proven to be successful for Northstar’s unique head gasket problem. Without this apparatus, no other chemical head gasket repair alternative is effective.
2018
Steel Seal Ltd developed some significant internal legal issues, a common occurrence in the industry, which required Robert to terminate the relationship. Steel Seal Elite was then rebranded back to Thermalweld.
