Now that the underside of the chassis is fully painted with satin black chassis paint I wanted to add further protection to the cavities that lurk within the MG Midgets monocoque chassis. For this job I turned to Bilt Hamber's Dynax S50 (Other cavity protection waxes are available) because it also comes with a very useful lance that evenly sprays the wax all around the cavity walls.
The main areas requiring treatment include the whole rear bulk head that is very easy to access with the chassis on its side. MG very kindly left these holes behind to make this job so easy! 😉 I also applied a coat up inside the spring hanger area.
I watched a couple of YouTube videos on how to do this to make sure I didn't waste too much of the product.
The idea is to insert the lance right to the back of the cavity, start to release the wax and then fairly quickly pull the lance out of the cavity. The Dynax S50 is quite runny initially to allow it to settle into all the cracks and joints. I choose to apply two coats as I can still remember how badly rusted this whole area was.
