Keel protection

[Kent]

I discovered that I lost a bump pad off of my trailer and as a result the keel has been rubbing on one of the cross bars. The fiberglass is scraped up pretty good right on the point of the keel for about 5 feet. I was considering buying a keel guard, but I have read that they shouldn't be applied where the keel will come in contact with rollers or similar. I have installed a new rubber bump pad and a keel guard would slide across the bump pad every time I launch or retrieve my boat. Are there any products that I can install myself that will protect my boat and last or if not can anyone recommend a place that can install a product such as Linex?
