Undersealing tips

[Matt2107]

My FTO has never been undersealed and has been in the country since Aug last year. I know I probably should have had it undersealed before the winter but I didn't have enough cash at the time.

Now the weathers nice I'm thinking about cracking out a paper suit and doing it myself. I'm not worried about getting it in my hair as I don't really have any.

Has anyone got any tips or recommendations to products?

I don't mind spending a bit of money to get a decent job. :thumb:

Make sure the chassis is 100000% dry and clean.
Undersealing over dirt/water/rust, speeds up the corrosion spread.....

Apart from that, slap it on... Lol

If you have access to a compressor and a shultz gun it will make the job easier and more effective and give a more consistent coat.

Brushing it on can give an unevencoat and leave small areas exposed.

I have a compressor I use for airbrushing.
Not sure if it'd be suitable or not.

Think its 40psi.

Any ideas of any rust protection/inhibitor products to use first?

Slap the hammerite on (couple of coats)

i would doubt it will supply enough volume if its for air brushing, the pressure will drop in about 2 secs of using the gun. and will probably struggle to lift it out the tin.

get it clean and bone dry as said, warm the underseal in the house or a basin of hot water so its runny, then spray away.

theres really not much to it. use waxoyl or simelar for the inside of cavities/chassis leg/sill sections. dont spray underseal on bits you wish to paint as the paint will disolve it, use stone-chip in these areas of beauty.

and dont apply it on mums lock-block ;)

I think your right about the compressor.

Looks like its 1/8 of a hp and only 50psi max with a few litre tank.

I did find a dinatrol undersealing kit.
£80 gets you a pre-rust inhibitor, first coat for flat areas, top coat and a product suitable for cavities plus a bag of plugs.
Shultz gun is another £10 on top so I might just phone round for quotes lol.
