rider Posted May 24, 2019 Share Posted May 24, 2019 My recommendation would be don't do it. I've had and seen enough older cars where the underseal has either failed or trapped in live rust that it really is something I now avoid like the plague. If you paint a surface or coat it with corrosion preventive then you can see if rust occurs or reoccurs. If you underseal or raptor coat then its out of sight is out of mind.

Did mine 10 years ago, had no problems, but it's not seen rain in 10 years Quote Link to comment Share on other sites More sharing options...
Scooter Posted May 31, 2019 Share Posted May 31, 2019 What do you recommend ? You could go with pressure wash, steam clean, removing bits that are easy (exhaust, exhaust heat shields, tunnel braces exhaust hanger bracket, tow hook tank guard etc), elbow grease in the hard to reach areas. You will gather the general state from the bits you take off and what you then uncover, as generally how often do we really examine underneath? I did this almost two years ago with one of mine, it was in good enough shape and I didn't plaster it with anything in the end, some dinitrol greasy stuff (under hockey sticks and rear brake duct/vents, I coated the tunnel braces in dinitrol under seal type stuff and por15'ed the exhaust heat shields and fuel tank cover. Also sprayed some acf50 around some places. I had a little look under the other day and may strip it again to see how it's faired. Quote Link to comment Share on other sites More sharing options...
rider Posted May 31, 2019 Share Posted May 31, 2019 What do you recommend ? I'd use POR paint or aquasteel on a prepped surface followed by zinc primer and a matt black or OEM colour paint. For tubular parts or hard to get to parts I spray Dinitrol 3125 which is a wax film corrosion preventive. That way you can see what is going on with the smooth top coat or wax film to know what is going on underneath. Quote Link to comment Share on other sites More sharing options...
Supra-love Posted June 2, 2019 Share Posted June 2, 2019 (edited) Got to say I’ve seen quite a few underbody restorations where they cover nuts, bolts, rubber grommets and even some of the lines. Which just hides things and makes things more difficult to remove later on although mine didn’t have rust anywhere, I made the decision just for extra protection long term, although it’s never used in the wet etc, I decided I wanted it done. I’m currently having my complete underbody restoration finished off now by little Num Will start a thread on the project with all the pics once complete Edited June 2, 2019 by Supra-love (see edit history) Quote Link to comment Share on other sites More sharing options...

Shane Posted June 6, 2019 Share Posted June 6, 2019 Thanks that sounds perfect It did for me too and maybe this is nothing, but may be worth checking out: https://beta.companieshouse.gov.uk/company/11177752/filing-history Quote Link to comment Share on other sites More sharing options...
tintinmt Posted June 6, 2019 Share Posted June 6, 2019 Unless you are going to drive it regularly in rain and particularly on winter salted roads I would not do it. Having said that (noting that you want a good job) doing it properly is not cheap as there is a lot of labour involved. Quote Link to comment Share on other sites More sharing options...
robin Posted June 6, 2019 Share Posted June 6, 2019 I have a UK car which has had to have a fair bit of work, stone guards replaced etc. I too share the concerns that a hard coating/paint can do more harm than good as it can trap moisture accelerating the rust and keeping any corrosion from view. My regime now is to apply some of this every year or two to the whole underside and spray into cavities and gaps. https://www.amazon.co.uk/gp/product/B0035KKK66 These creep oils get into everything and displace any water, the down side is that as they are a bit thinner they will eventually wash off.
