Default Polish molded fiberglass front panel x-139

The front molded fiberglass panel on our x-139 was not shining anymore and even had a yellow glaze color.

So I started up reading on fiberglass restoration and went all the way with these steps.

I started up by taking off the old dry out stickers. I used a rubber disk that I bought on amazom. It work great and it does a fast job.

Than I wet sanded with:

Step 1- 600 grit wet sanding paper
step 2- 1200 grit wet sanding paper
step 3 - 2000 grit wet sanding paper
Step 4 - 4000 grit wet sanding paper
step 5 - use a polishing machine with soft professional fiberglass compound paste
step 6 - finished with a boat professional wax (2 layers)

The process took me a complete day and I was doing the sanding by hand, could have been faster with a sanding disk tool.

The result is just amazing, got the original white gloss color back and it looks like it just came out of the dealer.

Here is a picture before and after and you can see the difference with the window panel that I will do next summer, because I had to winterize the unit.

Ps: hope my english is not to bad!!

Sounds like alot of work...but your results were excellent.

I've been using this:

Cleans well, goes a long way and maintains the "new" shine.

Nicely done! I wonder if an automotive clear coat would help prevent the yellowing like it does on fiberglass hoods and fenders?

(BTW - your use of English is better than mine! You have nothing to worry about)
