Some mobile home counter tops are very hard to replace but you can fix them with some car body fill.
In this picture if look to the far right you can see the laminate puckering. First cut away the pukering laminat and dig out the bad wood til you get to solid wood.
Next mix up some bondo it comes in 2 parts you don’t need very much of the hardener the more hardener you put in the less working time you have to smooth it out. Once it is hard you can sand it down to a smooth. Now come the fun part.
First sand all of your counter tops I use a palm sander. Clean off the counter top really really well. Then put 2 coats of primer paint when that dries put 2 coats of good paint on I used tan.
Then I put a third coat on the counter top and while it was still wet I through down these garage chips. The edge of the counter top I put the sprinkles in my hand and blew the chips.
I let it sit and dry for a day than I toke a putty knife and scrape off the top and sides of the counter top. Then I sanded with my palm sander. Put 3 coats of polyurethane sanding after each coat
And I have a brand new counter top that I LOVE LOVE LOVE. Easy peasy try it.
