  • Prepping trailer fenders for paint

    How would I go about getting my fenders ready for paint? Wetsand? Going to use this paint. The finish on my fenders is bad enough that I don't think they can be brought back.

    If they are not crack you might be supprised at just what can be done to dull gelcoat. I wouldn't rule it out as a possibility.

      Yup, before You paint it will need to have any cracks or imperfections repaired and sanded smooth in steps up to 320 grit. Then primer needs to be layed down and block sanded smooth in steps up to 320 grit and then wet sand with 500 grit before you lay down top coat and the clear coat. Its a LOT of work to paint those fenders to achieve a nice looking finish... so I would also recommend wetsanding the gelcoat first just to try bringing them back.

        Thanks for the replies guys. I will try to restore them first, but I believe I will probably have to end up painting.

          While your there can you measure the running light knock out? For both the amber and red lights and how big the light is? My boat is in storage and it would save me a trip. ('97 single axle)

                This.

                When you get it out take some good photos and post them up. There are some pretty smart guys here that could offer up better options if you show us what you are up against.

                  Will do guys. I found one from the day I brought the boat home last fall, it's not very close up though. As soon as I get it home I will break out the D5000 and get some good pics for you.

                    WOW!

                    (wished my fenders looked that good...)

                    My fenders have stress cracks, have damage to the tail light area, a tear from being side swiped in the parking lot and are a blue metal flake which is really hard to repair.

                    looks like you will have an easy time making those look like new again!

                      I would strongly recommend you do NOT order that paint kit sight unseen. I work for a major coatings company in the automotive refinish division. White is an extremely difficult color to match for vehicles in general and impossible to do with a pre-mixed kit off the internet. You would probably end up with shiny fenders in the end, but I can all but guarantee that it will be different enough from the rest of your trailer that you will notice it (it is amazing how a subtle difference in white can make such a huge impact when two panels are compared). The kit you are looking at is meant to be sprayed out of an automotive refinish spray gun. How are you planning on applying the paint? The kit also has a hardener with it which means that you have a limited amount of time to be able to spray the paint correctly before it begins to set up and solidify.

                      I would recommend visiting an automotive refinish store (also called Jobber store) and talking to someone inside. They will be very knowledgeable about how to prep correctly for adhesion and gloss and they will be able to give you an accurate match if you can bring one of the fenders to them. Fiberglass is not much different to paint on top of than bumpers on cars or other parts. Lots of people out there are building fiberglass hot rods and have been repairing Corvettes since 1953 so fiberglass trailer fenders are not out of the ordinary for an automotive paint technician or jobber store clerk to handle. I would also bet that someone inside a jobber store near you does paint work on the side in their house and they could do a great job for you if you don't have the correct equipment or skills.

                      I would be glad to offer step by step advice privately if you would like to tackle this yourself - just shoot me a PM.

                        What's a good way to remove the adhesive left behind from the slip guards on the fenders? I removed one last fall and the the adhesive didn't pull off with it. Was thinking kerosene may be good? I have a feeling they are all going to be like this.

                          Thanks for the advice. I'm planning on painting the entire trailer. Planned to use this HVLP gun from HF. I'm having the trailer blasted and then plan on priming with this, followed by the paint above. Not looking for showroom quality, just better than what it is currently, which shouldn't be too hard to do.

                            3M and other companies make adhesive removal products that are not too expensive that are designed to remove adhesive from moldings and emblems on the sides of cars. Kerosene or gasoline will work too, they just leave a greasy film behind that should be cleaned off as well. Not to mention dangerous to use. Anything that is solvent-based like mineral spirits, terpentine, paint reducer, etc. will all soften up the adhesive from the rubber pad enough to scrape it off with your fingernail. Be careful not to let any of these items get on stickers, vinyl or decals that are on your boat or trailer as they will distort and potentially discolor them.

                              If you have a small amount of ability with doing these kind of things, it shouldn't be too much trouble. The primer you showed is an epoxy which has excellent corrosion protection properties. These primers are designed to be applied to bare steel and the overcoated with a surfacer or top coat. Epoxy primer does not have to be sanded to be overcoated.

                              The gun you have linked up there will work for what you are doing, but keep in mind that spray guns that automotive paint technicians use cost $500-$800.00. Your compressor should be at least 2 HP to provide enough air for the consumption that gun requires (6 CFM - cubic feet per minute).

                              If you go slow, take your time and remember "less is more" you should do just fine. Don't try and put all the paint on at one time, you can always add another coat. Once it comes out of the gun, though you can't put it back in. There will be an adjustment on the gun to restrict the motion of the trigger. I highly recommend you turn that knob in at first until you get used to how fast the paint gets on the panel so you don't creat unnecessary work for yourself to fix runs. Remember to bend down and spray the bottom and the insides of the trailer as well. If you don't it will rust through on you in an astonishingly short amount of time.

                              Looks like a fun project that you can do yourself and will make a big difference for the looks of your rig. Let me know how it turns out and I will help any way I can as you get started.
