Just like when priming and painting your car there are a lot of choices when it comes to picking a seam sealer when refinishing or repairing your project. Seam sealer is made to cover and seal areas where panels may have been welded or overlapped. It will keep the seam from getting moisture in between panels and rusting out. As long as you use the correct seam sealer and prepared the panel correctly it will last the lifetime of the vehicle. We decided to cover the seam sealers that we offer and their best applications.
1. Brush on Seam Sealer- If you want ease of application and replication of the original brushable seam sealer is the way to go. It applies as smooth as you are careful when brushing it on. For best results we suggest using a stiff, quality acid brush as a standard brush will be messy and fall apart after only a few brush strokes. Use Eastwood PRE on your gloved finger and run it down the seam to smooth out brush strokes as soon as the seam sealer starts to set up. This is best used on areas of overlapping metal like trunk seams, floor pans, firewall, shock towers, etc.
2. 2K Self Leveling Seam Sealer- Want to take the mess out of applying seam sealer? 2K Self Leveling Seam Sealer is the easiest to apply and it layouts flawlessly every time. Cut your application tip to match the area you’re applying it to. Small hole will help apply small, thin beads to tight areas while cutting up higher on the tip will leave a large open hole that will apply a fat bead of seam sealer that will cover a larger area. We love this sealer for areas that we can’t get into easily to smooth with PRE and a Glove like a rain gutter or up under the dash. Apply it and it will level out itself with no work on your end. Most of your standard caulk guns will fit and make application a breeze.
3. Flexible Strip Caulk- – Sometimes it can be tough to apply traditional seam sealer to areas that are irregular like where heater core tubes, wiring, or AC hoses come out of the firewall. You also want something that might be a little bit easier to service if you ever have to get to those holes in the firewall. These flexible caulk strips can be molded and pushed into odd shapes to fill voids or openings that you don’t want to just seam seal shut. The best part is that these are paintable so they can be applied before final paint is laid down.
4. 1k Seam Sealer- Our one part seam sealer in the cartridge is a little easier to apply than the brushable and a lot less messy! But it is difficult to replicate the original seam sealer finish found on a classic car if you’re going for a perfect restoration. It does work just as well and can be applied quickly. Unlike the 2k it doesn’t self level, but using PRE on a rubber glove and running your finger down the bead of sealer will smooth it out. This is our go-to seam sealer and is the most user-friendly and cost effective. Perfect to seal up patch panel repairs, redoing old seam sealer joints, and much more.
