  • Best Chassis Rust Protection for Sri Lankan Coastal Weather?

Machanla, living near the coast (Negombo side) and starting to see minor surface rust around the door bottoms, bulkhead, and rear crossmember on my 90.
With our salty air and humidity, what's the best local solution to stop this before it eats through the metal? Are you guys doing chassis hot-dip galvanizing during full rebuilds or using specific underbody wax/coatings? Recommendations for good shops around Colombo/Gampaha are welcome too!

Bro, if you are doing a body-off restoration, galvanizing the chassis and bulkhead is 100% worth the money. Did mine 3 years ago and not a single spot of rust since, even with frequent beach runs

Ayo Ashan, Negombo salt air ekath ekka Defender rust control karana eka proper challenge ekak machan! 🌊 If it's just minor surface spots right now, wire-brush it down to bare metal, hit it with a proper rust converter like Würth, and flood the inner chassis box sections and door bottoms using a cavity wax like Dinitrol ML. Top the underbody with Dinitrol 4941 wax—never use cheap black bitumen tar sprays as they crack and trap salt water inside! If you ever do a full rebuild later, hot-dip galvanizing the chassis at LTL Galvanizing in Biyagama will freeze coastal rot for 20+ years. For a proper wax application without stripping the rig, check out Defender specialist workshops around Wattala, Ja-Ela, or Kaduwela. Weekend DIY job ekakda machan nathnam garage ekakata daannada inne?
