Right then we now need to rub down the primered bits ready to be undercoated so where do we start.
Tools needed
400 grit DA discs
Rubbing blocks....various
Well we will start with this ...the top of the hull
This is what I use a DA Disc....these come in boxes of 50 available from good automotive trade suppliers Ebay or call in to your local car repair shop and ask them nicely I am sure for the cost of some tea and coffe they will give you some.....10 will last you a long time....when they clog up simply give them a shake and reuse.
This is a quick rub down to see what we got to do
You will see a surface similar to the moon....This DOES NOT want filler on it at all.....All it needs is rubbing down properly.
Let me explain....imagine the surface of a saw...it has teeth yes we know that BUT think of all the highs and lows when you look sideways on the blade.....now if you painted this you would NOT get rid of the highs and lows so to speak as paint will not fill the lows BUT in fact it will.......what happens is paint will lie in the troughs without you realsing it and when you first start to rub down they seem to be there....BUT like Majic they will dissapear...trust ME it works.....When you are rubbing down the paint you are in effect leveling the substrate down....What you have to rememer is that the product that I am using is a Primer FILLER and is in fact thicker then undercoat.
2 mins of rubbing down and the troughs are fast dissapearing
5 mins later and YES they have gone....the blackish shadows that you see are simply the black colour of the plastic showing through and needs more primer filler applying to it
And here it is with Primer filler applied to it
Just to show you that I am using a product readily available to you all here it is....I simply walked into Euro car parts and picked it up off the shelf.....yes there is no dpubt about it it is darned EXPENSIVE at £12 a tin ....BUT trust me on this one....it is what they will use in any body shop for small repairs ....it is that good and can be rubbed down in around half an hour......I left this for a couple of days due to the sheer amount i put on......I troweled it on due to the imperfections on this moulding.......and be WARNED it dont half stink when applied and ALSO when being rubbed down.....U Pol/Wurth/Hycoate Manufacture similar stuff...PLEASE DO NOT thin this is the same stuff as the Yellow high build promer that Halfords sell far from it
The rest of the hull is in the process of being rubbed down and will have the same treatement before undercoat will be applied and Yes I will be spraying a guide coat of black ready for rubbing down
