Rustproofing

[111Robin]

The S50 has very good properties for seeping between panels and does mist in cavities as well so provides good coverage. It looks to be a good product however my cars are never out in the sort of conditions that would promote corrosion so I can't verify anything other than it should be good especially for condensation in box sections when garaged due to the coverage it gives. ie. It reaches a lot further than you can spray it.

i use Bilt Hamber "Dynax-UC" clear film anti-corrosion wax.. comes in a 750ml aerosol that will spray through 360deg; "If Needed" ..in my opinion great stuff & use it on everything not just bodywork for example drive shafts & suspension parts, etc... even use on paintwork stone chips on the daily car until i can get around to sorting the paint repair out .. If this stuff was edible i would have it on Toast

Impressed with their products, have you tried S50 https://bilthamber.com/product/dynax-s50/ as well ?

Just wondered what it was like

Their Hydrate 80 is good. for priming and where theres been rust.

I used some S50 on my mk4 last weekend-the lance is brilliant, poked it through each sill vent, it was dripping out of every vent when I’d finished

A good place to start with sills is to remove one of the forward facing bolts that hold the sub frame supporting bracket to the sill. Then insert a long probe (they call them 'straws') down the sill, right to the front. Attach it to the can, press the tit and slowly draw the can and straw rearwards. This ensures the the whole sill is drenched AND the bolt and thread is greased.

Then take the next bolt out the next week...... and do it again!

You can use the same long straw trick up the A and B posts too
