Restoration Tip - That old seam sealer has got to go!!

By precisionrestor

Seam sealer is a vital part of any restoration. It prevents leaks, prevents rust, and when done right directs the flow of water when caught in a rain storm or just giving your classic a bath. Over the years this seam sealer shrinks and become brittle, causing cracks and a great place to retain moisture eventually causing rust. In any restoration it is important to remove this old seam sealer as you may not know what is lurking underneath. These are just a few of the common signs that your seam sealer is failing and needs to be removed.

Obvious cracking, peeling and chipping is the number one problem with old seam sealer. As I mentioned before over time the seam sealer becomes brittle and starts to crack. This is usually very clear and easy to see in the drip rails above the side windows. The bead that is applied in this area likes to come off in chucks, leaving large section that is obviously missing material. If this is happening there is a good chance you will have at least some surface rust underneath.

Finding places of misuse is another reason to remove all of the old seam sealer. It is common to find seam sealer in rust holes is a low quality paint job or restoration. Seam sealer is a great way to prevent rust from seeping into and through seam on the bottom of a deck lid or door, but it is not a form of rust repair as seen in the below picture filling the rust holes on the Camaro deck lid. When the seam sealer is used correctly you should see signs of the lip or metal edge and not a heavy build up hiding these details.

In some cases the seam sealer may actually be intact and look as though it is in good shape, but it could be hiding rust. In the picture below of the Mustang, the black seam sealer was fairly intact until we took chisel to it. When we did this it all fell off revealing the rust underneath. If this were to have been just sanded and painted, we would have just sealed in all of that rust.

You will find seam sealer everywhere on your car. On almost every welded body seam, on floors, quarter panels, deck lids, and doors the old seam sealer needs to be removed and reapplied to prevent rust and leaks. Just as with any other repair, replacing old seam sealer with new ensures a long lasting restoration.

1987 Chevy Pick up - Restomod restoration

By precisionrestor

Filed under: /blogs/browse/t/vehicle/v//p

This is a Restomod we completed here at Precision Restorations just a few months back. The truck showed up mostly disassembled with many parts in boxes. It is a great example of how the looks and performance of a vehicle can drastically change with just a few modifications. Custom paint and stripes, custom grill, a Ram Jet 350, custom rims, and dropped springs and spindles give this truck a whole new look when compared to stock.

The interior remained fairly stock with new carpet, headliner, dash pad, and a fresh coat of paint on the dash. This build also included Dakota Digital gauges and a Rostra Cruise control kit.



This late model Chevy drives just as good as it looks. Crusing with the windows up and a/c on made this truck a great year round hot rod
