OK this might be a stupid post but Im finding it difficult to see where I've applied product on my liquid blue A4. Liquid blue is the very light baby blue colour. I applied meg's liquid wax with my DA and I couldn't see if I missed any cause the product is almost clear and doesn't show up on the light paint. I hope Im getting my point across cause its hard to explain. Is there any coloured products such as liquid waxes, sealents etc that are coloured dark so you can see them applied onto light coloured paint? People with white cars must have the same problem?
