Your trailer isn't worth what to whom? How much will it cost to replace it? If the repairs are less than a replacement, would you keep it? The answer is yes it can be repaired. The unknown is how much damage is involved, and what the resulting repair costs will be. Screwing plywood to the inside of a delaminated panel is akin to placing a bandaid on a broken limb. It will add even more weight to the already heavy trailer and offer little or no structural improvement. Without getting technical, a FRP repair with a plywood core involves a few steps. If the delaminated areas are small and don't involve a whole panel, they are identified and marked. On the inside, a trim router with a straight bit cuts away the interior FRP of the involved area and it is removed. The bit depth is set so that it does not contact the exterior FRP skin. The rotted wood is removed, and a new carefully crafted piece is fitted and epoxied in place and to the outside skin. The inside FRP skin is replaced and the whole wall is then painted to match the original. The outside skin is left intact and undisturbed, to maintain the original looks and integrity. Any marina that offers fiberglass boat repairs can effect your trailer repairs. Repairing cored fiberglass construction is a common practice for these businesses. Most boat yards in the NE command at least $65-$75 shop hourly rates plus materials. Again in the NE, around the middle to the end of Oct., many boatyard labourers will receive layoff notices. Their wages are typically in the ~$20 range. Many of them welcome under the table jobs at those rates. Your repairs could range greatly in price, depending on their volume and numbers. Even if they approach the thousands of $ range, can you purchase a replacement trailer for that amount? You need to talk with and show your trailer to, someone who is competent in these types of repairs, so you can make an informed decision. BOL |
