Undersealing/and cavity protection.....and being careful who you use

[Mazda Mender]

5 to 6 for undersealing depending on how good you want it and mark, around 5 for cavity depending on mark.

It is almost new and I have a can of RC900 and 2 of Dinitrol cavity wax. Just wanted to buy the necessary as I don’t have too much room for stuff I don’t need

I ordered 6 cans of this for my 10AE https://www.ebay.co.uk/itm/4x-500ml-Qli ... 4376149290
Have to say it comes out quicker than I expected so ordered a 7th can (only had a little left in the 6th can when I got to the doors/boot lid).

For closure, last winter I put right what was missed following the excellent M-m guidance and quite enjoyed the process too.

I should add that once this process is done, you do need to check it every 12 months, there is no ultimate cure for tin worm no matter what anyone says or uses, having this process done and the undersealer telling you it is "done for good" is rubbish ,the process is about "managing" the rust, and nipping it before it ever becomes a problem, so once done "if" you spot a tell tail sign for what ever reason, you will only need to sort that area and re seal (managing).
There is a chap at the minute that states that "all" the old underseal needs removing before doing anything, a good time served access er will tell you that this is rubbish and scare tactics to extract more money from you, a good time served access er will know the traits and problem areas from years of doing it and knowledge that is second nature, there is the exception where it will need removing if brought back up from the Mary rose or lived it Scotland, but that is where the skill and knowledge come into play whether it does and the owner informed , If you want it all removed then that it solely down to yourself, but is not needed,don't be taken in by scare mongering and sales waffle.
Any undersealing that as been done in a day will and is rubbish , it will have nothing removed and sprayed over rust and plastic guards trapping it in, waste of time and money.
Now for some reason unknown ,i seem to be under attack for " doing this in a drive way",correct and that is the point, because that is where most of the ownership are ,personally i don't see the issue? it does not matter where this process is done as long as it is done correct, i think what they are missing is that i am proving that a good standard can be achieved by anyone, regardless of where they have to work, if i can get this level of work done to this standard outside on a drive way relaying on the gods being kind to me on weather, anyone can, and thats the point, its not about me, its about the other owners feeding off us to be confidant enough to tackle what ever job we show to keep these on the road as they get older ,correct and to owners personal budgets, we are here to help you and save you money the best we can , if we can guide you to do some of these jobs , what ever it maybe , because our knowledge does not just stop at this subject unlike others that do like to attack, we have a lot more wide spread knowledge we are willing to share with everyone, use us, its what this is all for.
