For health and safety reasons paint strippers no longer have dichloromethane as the active ingredient. That is why Nitromors and all the other DIY store strippers are now pretty useless. If you search for "Industrial Paint Stripper" then you will find the original dichloromethane stuff.
I would advise against grit blasting, it is far too severe for metal panels which will warp under the heat and force. Soda blasting, a similar process but much less intense, usually gets excellent results, especially if done by an expert. Classic car restorers use it all the time. Soda blasting might struggle to remove extremely thick paint, and it's not good at removing encrusted grease deposits.
