Thermal heating and blasting

I think @grumpynorthener might have had this done?

I Have indeed had several bodyshells along with a huge amount of panels bare metaled with this process - basically the shells / panels are heated through a staged process over a lengthy period to between 350 - 400 degrees - this burns off the majority of the paint / filler / sealer / underseal but you will also loose any body solder or lead from factory joints - the shell / panels are then staged cooled - done correctly and to the book there is no detrimental effect to the shell / panels - these are then washed off and then stage immersed in phosphoric acid to remove any traces of rust - before being washed off & immediately oven dried - the process is referred to has 'Pryolysis'

There are several players in this market but only one that I trust - I have heard some hideous stories of other companies that use much harsher & higher concentrates of acid dipping to accelerate the process which give very unsatisfactory results with paint finishes several months after you complete your restoration (read acid trapped in body seams attacking your new paint finish) - they all have you sign a small print disclaimer and you don't stand a chance of getting back at them afterwards

The problem with what your guy in Halifax is offering is that it is not a full stage process - sure the cars panels will come back devoid of paint / filler etc and it gives you a clean sheet to work with - however if the car is only going be lightly blasted only the panels that can be accessed can be blasted - what about all the hidden box sections & cavities where untreated rust is still lurking ?

For me it would be false economy - if you are going to this extent to bare metal you might has well do it properly - 'Envirostrip' at Tamworth are the only people in this line of business that I would recommend - it's also the company that Car SOS / Fuzz Townsend uses and is in the above postings video - they have a nationwide collection delivery service and can offer you the option of coating the shell & panels in a 2k etch primer should you wish once the process is completed

Here are a few pics of a Jowett Javelin that I did a few years ago using Envirostrip





I was with car last weekend which now resides in Switzerland and still looks fantastic with absolutely no adverse effects on the body seams etc

I have no direct connection with Envirostrip - like the rest of my suppliers I use them because I can trust them to do what I need them to deliver to a high quality standard
