Undersealing / undercoating

[shad0wca7]

With my Z (53 plate) getting on a little. Let. My thoughts turn to preservation as well as enjoying it.

What are the thoughts on undersealing / undercoating? Especially in the wheel wells.

What kinds of costs would be appropriate for a garage to do it?

I was charged £200 for clear undersealing my 380RS - even though it won't ever get used in bad weather - wondering if there is any value is in underselling a car that's probably seen the worst of the UK weather - unless of course you've been keeping it out of the snow & salt since new?

 

Just a thought

I cleaned up the wheel wells and under sealed on my 53 plate just to help it stay in good order.

I removed all 4 wheels and removed all the dirt, I didn't remove the front wheel arch liners and the rear arches are pretty exposed with no liner as such.

 

I then coated with Hydrate 80 from Bilt Hamber before applying a couple of coats of Smoothrite black, using a combination of brush and spray.

 

I know it's not everyones cup of tea to use Smoothrite but I use it on all my cars and re-coat every 3 years or so, that said although the Z is my daily runner being self employed I don't do a massive mileage because I generally work from home so the car will not be subjected to heavy winter use anyway.

 

I removed the W brace and cleaned / re-painted using the same Hydrate 80 and smoothrite, I then cleaned and re-painted the underside as far as possible up to the sill edges with any bolts removed ( inc underneath covers ) being treated with copper grease before replacing.

 

I could have used a local company to clean and waxoyl the underneath but I'm not a massive fan of that stuff being applied underneath to be honest, but I did a wheel arch a day and I suppose including coating all exposed bolts it took me a couple of weeks to complete.

 

For me doing a bit at a time means the job doesn't become a chore and spending 4 to 5 hours at a time is enough.

 

 

 

Also started to clean under the bonnet and starting to look better.

That's some nice work Gerry40. Good idea on doing a bit a day - I'll think about doing it your way.

Waxoyl is a awful stuff. Gets everywhere.

Although it's good for putting into chassis rails and sills.

 

Personally I'd coat the underside of a car with POR15. Very good stuff.

Smoothrite isnt an underseal you still need to underseal over it

 

Epoxy paints like POR15 are very good to coat unprotected areas , my Evo had unlaquered body colour underneath in places . I spent 2 weeks one Christmas doing it , took the fuel tank and exhaust off and everything, I used an epoxy paint , then shutz underseal and finally brush on underseal in nooks and carries

 

When I did my R33 the protection behind the wings was like this ie nothing

 

 

 

 

I used a rust protector , then smoothrite, then anti chip compound and finally wax

 

To do it properly is a really big and really messy job , if you want to get a company to do it there are loads of 4x4 specialists that are geared up for it and can do it for a reasonable price

There are cheaper products on the market but Teroson is by far the best!
