DINITROL RC 900 is a rust converter based on an organic chelate complex combined with epoxy resin. It actively converts the rust on the substrate into a stable organic iron complex. When the product dries, it forms an impenetrable barrier to further corrosion. DINITROL RC 900 penetrates about 7-10 times deeper into the rust than conventional rust conversion products and forms a dry and strong adhesive film that is suitable as a base for the lacquer structure and as a carrier for other corrosion protection products.

HOW TO USE
Step One
Before starting the DIY rustproofing wash the vehicle from dirt and grease and allow to completely dry
Once dry, mask up any areas that you do not want to spray. Wear suitable protective clothing and place plastic floor covering under the vehicle to protect the surface from product drips. You may also require a wire brush to remove any loose material to find the solid base metal.
Step Two
Treat any rust present on the vehicle with the specialist RC900 Convertor product
Remove any flaking rust and apply the DINITROL® RC900 Rust convertor to the remaining rust making sure the edges are coated to ensure a good seal. This will convert rust into a stable organic iron complex. Drying time is up to 24 hours
Step Three
Spray ML cavity wax into all vehicle underbody box sections
Using an injection pipe or extension nozzle start to inject the product into internal bodywork and chassis cavities. Please note injection pipes or extended hose are for cavity wax applications only and not for applying vehicle underbody coatings. Drying time is up to 2-3 hours
Step Four
Also apply a thin coat of the ML cavity wax to the underbody of the vehicle
Spraying a thin coat (light misting) of cavity wax prior to applying the underbody coating softens up any existing coating that may be present and helps with the adhesion of the underbody or stone chip coating. Cavity waxes also contain rust inhibitors whilst the underbody coating combats the highly corrosive effects of road salt and abrasion. Does not have to dry
Step Five
Apply the underbody coating 4941 over the underbody cavity wax layer, this can be done while still wet
In some circumstances when working in a cold environment it may be necessary to warm the underbody coating (up to the room temperature) prior to spraying due to being much thicker than the cavity wax. To obtain the optimum protection a typical thickness of 2mm wet should be applied this will dry to around 1mm. Drying time is up to 12 hours
Step Six
Finally remember to clean any excess or overspray from the vehicle
To clean equipment use Benzene based spirit. Your vehicle is now protected from corrosion, please remember to inspect the underbody annually and touch the coating where necessary to check the surface in more detail.
Drying times may vary based on the environment. Times are estimate based on dry, room temperature environment ,

Simple AND essential, everyone should read
Format: Kindle
I've been Christian for many years, reading many books, sermons, biblical readings, but we never stop having more beautiful insights of this glorious Christian path laid before our minds and hearts. This book is a wise, beautiful, encouraging, and simply amazing way to see and live out the Christian life and calling, rich with meaning in our current broken world and the redeemed and restored world in Christ. Are you yearning for real spirituality, joy, justice, beauty, relationships, but they seem somehow out of reach? Read this book. It is simple yet profound. Take the time to savor the words of this book alongside prayer, biblical reading, community, daily work...And partake in the overlap of heaven and earth with the Lord.

Why "Simply Christian" is a "must read"
It presents a compelling case for Christianity without attempting to bully the reader (as C. S. Lewis often does in his essays) and without relying on all those "code words" that long-time Christians find familiar but others do not. This is the Gospel in plan English. Bravo! It firmly insists that Christianity makes claims about history - that Jesus lived, died, and rose again, and that this resurrection is the central event in the story of God's re-creation of our fallen world. It insists that Christians be active participants in the future unfolding of God's plan. We are each called to play a unique role in it. It insists that there is a transcendent realm, another world, that can and does intersect or overlap with our own world, especially in sacraments, in worship, in Bible reading, and in prayer. Moreover, just as the temple was, for Jews in Jesus time, a place where heaven and earth overlapped, now we, as individual Christians, are called to be such places of overlap, where the light of Jesus shines through us. It highlights the crucial importance of forgiveness. Just as God has forgiven us our sins, so are we to forgive others. The Lord's prayer is explicit on this point. Becoming a Christian, Wright asserts, is not a matter or accepting certain improbable factual assertions, but rather a matter of trusting in God and accepting our role in unfolding his plan for the world. Rather than being dissected, as in a laboratory, or treated merely as an instrument of historical or linguistic research, the Bible is in fact one of the principal ways in which God addresses us, to prepare us for our role in fulfilling his ultimate plans. It is another place where this world and God's world overlap. Current debates over "literal" versus "metaphorical" ways of reading scripture are, in Wright's view, counterproductive. The Bible eludes these simplistic categories, which should be abandoned. At its core, then, the "faith" to which the Bible calls us is essentially trusting in a God who has revealed himself in history, who has begun, through Jesus' death and resurrection, to redeem the world and transform it into his kingdom, who invites us into to an intimate relationship with him, who demands that we become all that we were created and meant to be, who forgives us when we fall short of that mark, and who invites us to play a significant role in moving forward his plan for the world. For Wright, Christian faith is not just a matter of spiritual feelings that are quite independent of what we say and do. It makes demands upon us that can only be met in the realm of thought and behavior. As C. S. Lewis did in his fiction, "Simply Christian" persuasively invites its readers to recognize that there is a transcendent reality that impinges on our ordinary world, that the God who rules this realm has made himself known in history and continues to do so, that we are part of his plan to renew his creation, and, consequently, that what we think and do has cosmic significance.

Interesting, but no Lewis
Format: Paperback
Some books can be completely conveyed in about eight sentences or a couple paragraphs. This is one of them. Everything else beyond the core thesis is unnecessary or repetitive. This book probably would have made a good article. Wright is a well known Pauline expert, but in this book he takes a step out of his comfort zone. I usually find Paul rambling and confusing enough, so I look to experts like Wright to clarify Paul for me. But in this book, Wright seems to put on his Paul hat and just reiterates Pauline gobbledy-gook. Throughout, he presents long passages comprised solely of Pauline quotes. This book is billed as an updated version of C.S. Lewis’s “Mere Christianity.” Both Wright and Lewis are seeped in their Anglican tradition. But where Lewis looks at the various Christian denominations and identifies what’s common and good among them all, Wright sees differences and insists they are all wrong. In alienating evangelicals on the one hand, and Catholics on the other, Wright suggests that to be Simply Christian you must abandon your faith traditions that are at odds with his. I can’t imagine Lewis taking this tack. I give this three stars, for its clear style, for being thought provoking, and for its call to personal introspection.
