Acid Dipping body shell

[mk1]

Doesn't "Thermal Pyrolysis" sound better than "Cook it in an oven with the door closed"

I used ProStrip in Nottingham, and it was around £1150 delivered back to me in a covered trailer (it was January and even though their anti-rust coating is damn good, I didn't think 150 miles on an open trailer was a good idea), and the delivery was £300 ish of the overall price.

Next one I do will be e-coated for sure, the extra cost is a small amount of the overall rebuild total but gives you peace of mind for a decade or two.

In the past I have had shells and panels dipped and e-coated. Not too long a go I had the shell of a customers car done and the shell of my 1071 was done too.

Here is a picture of the way they come back when it has just gone for paint and rust removal. The shells are dipped in several acid solutions for about 4 days in total and rinsed after. I deliberately went don that road as the body work needed to be done and I wanted it to be done correctly, in other words not by the party that the dippers use for doing the body work.

It comes back very clean and if there would be any weeping then it will show up.

Once the bodywork is done and the shell goes back for the e-coat, it turns out looking like this. As there is no more acid involved just rinsing and coating you are sure that there can't be any weeping after either.

Now I do need to mention that this is done over on the mainland by a company based in the Netherlands, their processes might differ to the ones used by the UK based ones.

I've had the last two projects dipped by Prostrip in Nottingham and been very happy with the results, I've had so bleeding issues etc either. I have had some horrific experiences with blasting and would always dip these days.

Thank you for all the reply’s,

I’ve put out for a number of quotes so we’ll see what comes back!

I had my GT shell done by Ribble Technology that Catmint mentions.

They use a thermal process to remove the paint, filler, organic material and then a dip to remove the rust. Followed by a phosphate wash to neutralise the acid and leave the shell with a zinc rich coating to prevent flash rusting (which works really well - mine sat for weeks before being painted).

I was really happy with the result and the price (and wait time) were nothing like the ‘big names’.

I was looking at getting them to do a shell soon.

I was at my body shop a few months back looking at the 59 shell he's just finished for a member, that had been dipped by Ribble, I wasn't impressed. It had only been back 3 days and was already showing signs of surface rust. With Prostrip I've had a shell sit for 6 months with nothing happening at all.

If you look at the scuttle it's already going brown.

That shell look like it either wasn't washed off with the phosphate stuff or it has been power washed off once returned - I had none of the heavy white run marks on mine, just a clean dull grey finish.
