Can anybody recommend a specialist who could sort out rusty chassis tubes and power coat the whole thing.
I have heard that certain specialists are not to be trusted so I don`t know who to use.

Thanks

if you are in the essex area try Tysons at Rawreth who can shot blast the chassis and carry out the powder coating, not the cheapest but very good

Peninsula have done a lovely job on my chassis and I think they do free collection.

Check out the SEAC Rebuild link from http://go.to/tvrbristol

Just a couple of thoughts on powder coating and the alternatives.

Powder coating is good if done properly but as any TVR owner knows, once the coating is broken the rust spreads underneath, often without being obvious until it really gets a hold. Weld bi-products also cause it to lift and crack which is why most TVR chassis corrode at the welds first due to poor pre-coating preparation. The coating also needs to go on as soon as the shot blasting has been done. Problem is once it has split its very difficult to repair as normal paint wont seal properly to the powder coat around a damaged area = more moisture ingress = more rust.

You could also consider zinc dipping but that is a hot metal process and I would personally have reservations about chassis distortion as a result of the heat.

Finally, good quality heavy duty paint with a rust inhibiting primer is not as tough as powder coating but its easy to re-paint damaged areas so, provided you are prepared to give it an annual touch up and waxoyle, is probably just as good in the long run and easier to maintain than powder coating - especially in exposed areas.

This being the case I'm about to put my money where my mouth is and have my chassis painted and waxoyled (internal and external) after shotblasting. Work is being done at David Geralds and I will report back on the results.

PS. Suggest you get more than one quote, cheapest is not always best and remember to ask how long they will need your car for (especially if you consider using Peninsular......!)
