Cracked Bumper, Snapped Trim Clips? The Body Repair Tools to Use

A trim clip snaps, a bumper cracks, or a new door skin needs folding over the frame. Each job has its own tool: nylon levers for trim, a plastic welder with matching rod for bumpers, and a folding (hemming) tool for door skins.

The Body Service Tools range at PartsForMachines has 35 products from Sealey, Sykes Pickavant and Draper, including trim tools, a cordless plastic welding kit, door skin tools and filler spreaders.

Are Cheap Plastic Trim Tools Good Enough, or Is a Better Set Worth It?

A basic set will do, provided the tools won’t mark the panel and you have the right shape for each fixing. Nylon is kind to finished trim, and a bigger set gives you a lever, prise or pull for each clip rather than one tool forced to do everything. A 12-piece nylon trim removal kit such as the 22492 is made for door panels, dashboard fascias and trim strips.

Keep a hook and a wedge for the awkward bits too. The 04552000 set pairs a universal hook for door mouldings and seals with a wedge that slides behind a panel to free its clips.

Cracked Bumper: Plastic Welder, Hot Staples or Fibreglass and Resin?

For a crack right through the bumper, a plastic welder that also takes hot staples covers the whole repair. Pull the crack into line, then reinforce the back first for strength. Then grind a V-groove along the front and weld it with rod that suits the plastic.

A cordless plastic welding kit such as the SDL14 has a hot staple tip, 0.6 and 0.8 mm flat staples, mesh sheets, welding tips and rods. Resin from behind works only if it sticks to that plastic, so check the type first.

Why Won’t the Weld, Staples or Resin Hold on My Bumper?

A repair that won’t hold often doesn’t suit the plastic, so identify it first. Look for the code moulded on the back of the bumper, such as PP or PUR: it tells you which rod to use, or whether it will weld at all. No code? Test which rod sticks. The SDL14 comes with ABS, PP, PE and PS rods.

Some urethane (PUR) bumpers are thermosets, which don’t melt, so staples and rod can’t fuse into them; those can be repaired with a plastic repair adhesive instead. Resin, filler and adhesives often need an adhesion promoter to stick to bare plastic.

Reskinning a Door: Do I Need a Proper Folding Tool?

Not strictly: a hammer and dolly will fold the flange, and a hemming tool can do the same job in their place. Work in two stages: take the flange part way over along the edge, then trial-fit the door and check it before you close the hem flat or weld anything.

A 320 mm door skin folding tool such as the RE92/33 is designed to preform and finish skins onto door frames. Sealey fits it with a nylon pad to stop the panel deforming as you fold.

What Should I Check Before I Buy?

the job, and a tool made for it: non-marking nylon for trim, a hook for mouldings and seals
the code on the back of the bumper, and a welding rod to match it
on a cordless welder, the run time and recharge time against the size of the job
on door skin tools, the length, jaw or pad width, and whether pads can be replaced
for filler, spreader widths to suit the repair, and sprung steel or plastic

Frequently Asked Questions

Should a new door skin be welded all round, or bonded?

Follow the vehicle maker’s repair method for that door. Many skins are now secured with structural adhesive along the hem flange rather than welded all round. Where you bond, run adhesive over every mating surface in the flange so there are no gaps.

Can I replace the worn pad on a door skin crimping tool?

Yes, on tools with replaceable pads. The 04310000 door skin crimping tool uses replaceable nylon pads and comes with a 50 mm pad for straight edges; that pad is sold on its own as 04310270.

How can I hold a bonnet, boot lid or panel in line while I fit it?

Use inflatable panel bags. They slide in flat, just 2 mm thick, and a fine air control valve lets you inflate them to ease the panel into position. Each bag in the VS9111 to VS9114 sets is rated at 135 kg.

Is a general trim set enough, or do some door jobs need special tools?

A general set covers door panels, fascias and trim strips, but some jobs need make-specific tools. The VS189 removes and refits lock cylinders on a range of VAG cars; the VS805 kit takes off hinges and handles on VW, Audi, Porsche and Mercedes doors.

Should I have spare trim clips ready before I start?

Yes. Clips can crack or snap as they come out, especially if they’re forced with the wrong tool. Pull one first, match a replacement to its type and size, and have a few spares to hand before you strip the rest.

How do I remove badges or decals without scratching the paint?

Use a plastic scraper rather than a metal blade. The AK5251 set is made for lifting trim, badges and decals, and Sealey says its polypropylene edges won’t scratch or mark paintwork and can be resharpened with a file.

Plastic or steel filler spreader: which should I use?

Either works; it’s down to how you like to work. The sprung steel blades in the 46449 filler applicator set flex evenly in 50, 80, 100 and 120 mm widths. PA03 plastic spreaders come 25 to a pack, so a clean one is to hand.

How do I keep a filler spreader clean between passes?

Clean it straight away: mixed filler only stays workable for a few minutes before it starts to set. Scrape and wipe the blade between passes, and if filler has begun to harden on it, swap to a fresh plastic spreader.

How long does a cordless plastic welder run on a charge?

It varies by model. Sealey rates the SDL14 at up to 40 minutes per charge, with a 3.5-hour recharge through its USB lead, so on a long job plan breaks to recharge it or work in short sessions.
