Underseal/rust. Idiots guide please

Had a wee look under the car the other day and noticed a bit of rust,plus the underseal didn't look to great.
I've organised the loan of a ramp next week (thanks QuickShiftMotorsport) and was looking for some advice on what's the best way to prep,what products to use etc.
Are their any kits out their,or traders on here who sell the products I need.

Cheers guys.

Davie, big job breaking out if you're gonna do it properly... messy PITA of a job to do..

Stay away from the pish black underseal would be my advice.

Have a look @ Dinitrol products.

Thanks for the reply mate.

Done a wee google search on dinitrol and came up with some good info.
Are their any decent suppliers of this stuff or is it an eBay buy.

Also,what is the best process,clean,prime,rust-proof etc.

Like the title kinda need an idiots guide.

You need to get rid of whatever underseal is already there, plus any rust, with a wire brush drill attachment thingy - if you can get an air pressure one that would be better.
Once you've got rid of all the cr4p, spray with some de ruster, then underseal with whatever product you choose. I used two coats....

No probs Davie

I'm no expert by any means but doing it right is not no easy job.

First thing I'd do is carefully steam PW the underside thoroughly and inspect the car and see what job you have on your hands. Ideally you need some one to inspect it that knows CP9A's inside out. I'm sure Steve @ BP would be the right man to ask for this.

Best off having a shop around for Dinitrol.

I'll have a look for some Dinitrol offers for you when I've had my tea Davie.

Cheers guys.

HP yir some man,I'm on my phone atm and its really slow.

I'm changing the exhaust at the same time so thought it would be a good idea to clean underneath while it was off.

Got access to an air line also.

Thanks.

Might be too much for my knowledge mate

How long do you think that will take you Johnno?
Do you already have the products to start

Took me two weeks

I had the car up on axle stands dropped the fuel tank, removed the exhaust and got in there, mine only had very minor surface rust

I cleaned everything up with drill/grinder and wire brush

Treated any rust with Bilt Hamber De-ox gel

Then treated with KBS rust blast and then KBS silver paint (You would need to hammer this stuff off !!)

http://www.therustshop.com/shop/inde...d&productId=51

Then re-undersealed the car with Shultz underseal

Finally applied a coat on top of brush on underseal as you can really work it into the nooks and crannies, I inspect and top up with this every winter

Any chance you'd do mine?
