Clay bar question.
 

Gave car a wash then clay bar on bonnet and boot,big improvement,but i want to give it a 2nd go if weather holds up tomorrow. I polished after clay bar,so will i have to wash car again or can i clay bar over the polish.

There's no polish left on the car, it's fine to clay it without washing unless it has gotten dirty

Personally, I would wash it, even if it's just a hose down and not dried, to reduce the contaminants the clay will have to remove.

Blue tack works well for me John and a lot cheaper ;).

Hi,

i'd give it at least rinse off. You want all the dust etc. off before you clay otherwise you'll be "grinding" the dust into the paintwork as you clay.

Many clays can be used with a diluted shampoo mix which aids/lubricates their action.

Have you done the "plastic bag" test? Get a cheapo bag - the sort of thing you put fruit/veg in from the supermarket is fine.

Put you hand in and pull it tight across your fingers.

Gently feel across the surface (after washing/rinsing so no dust).

If you can feel a "gritty" surface it needs claying (again); if not, it doesn't.

Hope this helps.

Good luck.

Andy

You'll find me on there quite a bit :}:}

Done bonnet and boot 2nd time today,although pleased with yesterdays result,more dirt picked up again. May do it 3rd or 4th time if it stops raining.
Nothing better to do,retirement is so BORING.;)

Retirement is great John, don't knock it, I haven't missed a Lion's match yet :bowdown:}:}.:

When i was working i would look out to what shift i would be on when football or any sport was on in next few weeks. Now i am on same shift all the time never miss anything.:D

For the clay bar to be fully effective i'd remove everything thats on the paint.
Before clay bar, I would use a tar & glue remover.
