Old protection/New protection.

[ash0098]

When applying new protection does it matter that some of the old stuff is still there. Will it make much of a difference to the finishing result? Should i just go ahead and do it or take the old stuff off first. Did it a few months ago but starting too dull down again now so about ready for a fresh coat.

Any good methods or best way to do it would be much appreciated

i take it you mean the bodywork if so debo is the man for your answer here but there is a good compound that will restore and protect against uv rays

Hi Ash,
There's nothing to stop you putting new stuff over old. Ideally you want to stick to applying the same product, as this new layer will act as a "top up". However, if you're thinking of switching products, it's best to strip the existing/remaining protection off, so that the new product can bond directly with the paintwork.

To remove any protection, you can clay the car, which will also help form a good base to apply protection on - or if you haven't the time, you can just use fairy liquid in a bucket of water instead of normal car shampoo, this will strip it off.

Cheers Matt, it will be the same stuff i'm using again. I just wasn't sure if it would affect it in anyway.
