Buzzweld Cavity paint and purge kit.

Developed specifically to offer an alternative to cavity wax injection. Buzzweld Cavity Paint injects an industrial grade corrosion modification solution into the chassis offering long term stabilisation of the internal structure.



  1. Stablises and modifies corrosion
  2. Superb creep and wetting out properties
  3. Compatible with zero prep cavity system as a pre treatment for 100% coverage
  4. Protects and defends against rust creep
  5. Simple to inspect, low build solution
  6. highly resistant to force cleaning such as internal jetting
  7. Comes with aerosol, lance, spray nozzle unblocker kit, and Buzzweld Purge aerosol.


Purge Aerosol.

The purge aerosol can be used to clean the lance out after use, and also to help emulsify wet wax coatings within a cavity where you cannot reach prior to washing it out with clean water. Care must be taken not to allow the Purge fluid to get on to existing paintwork as it is an aggressive solution.

If the cavity is clean, then there is no benefit in using it.

Application Method.

  1. Apply the purge aerosol to the cavity through the lance and leave for 5 minutes.
  2. Wash out the cavity with water
  3. allow to dry for 24 hours
  4. Apply the cavity paint in two or more  separate doses giving two or more effective coats internally.

Can be topped up with zero prep, or W.A.R. to add build, and VCI protection for belt and braces.

Cavity paint and purge kit
Sunday, 28 May 2017  | 

After advice from Craig I ordered this kit, found the purge sprays easy to use, the lance very good with a good spray pattern in all directions, haven't used the Cavity paint as yet but like all Buzzweld products i can see it working well.

Tried this out the other day for the first time. I used it to coat the inside of my tubular outriggers and my rear A frame x member. On the outriggers I found a bit of a tap with a screwdriver removed any flakes of rust and then a blast out with the purge evacuated the loose flakes. Purge dries insanely quick and then a quick blast up the tube with the cavity Lance and I was done. Really easy to do, it's satisfying watching the paint coat the inside so evenly as you puce the Lance up. The x member had the same treatment. Although coating blind I used the purge with Lance to spray in every direction conceivable left for 5 min and then did the same with the paint. I feel confident most of the internals are now painted. A quick blast of purge through Lance and it's clean for re use. I still have more than 1/4 of a tin left so once I've done inside front out riggers I may go back for a 2nd coat with what's left.

What awesome stuff!
Friday, 23 December 2016  | 

Okay, i was a bit cautious about what i buy for my defender and where from. I had my eye on this cavity paint kit for a while and no one wrote a review. So, here it goes. I used this on my 1990 200tdi defender 90. I used the purge kits inside the chassis along with a steam cleaner to get the most out that i could. Left it to dry for a while, once dry i applied the cavity paint (5 aerosols) through all the holes i could get to and wow. This paint goes on so well. It literally forms a nice mist and ,along with the long paint tubes you get with the kit, this stuff gets absolutely everywhere within the chassis. After it had been sat a while i went to every chassis hole i could get to to check the coverage and it had covered perfectly. From this day forward i will not be buying any other product other than buzzweld. Fantastic product, fantastic service and a fantastic chassis.
