Extend hood edge

[bil1024]

I over trimmed the hood to the main body, so need to build up again. Guessing have to use fiberglass filler to extend the bonnet ? Thoughts ?

I think many would probably say that in order to do it 100% right you should build it up with fiberglass cloth (especially on an edge). But I think technology has come a long way and modern glass fillers are actually pretty amazing these days.

This might give you some ideas on a technique.

A lot of people in the comments give him crap for it, but I've seen another video where the folks from Eastwood say to ignore them— they wholeheartedly endorse his method and stand behind it. That is part of another video with the same guy at the Eastwood factory shooting another how-to video on the technique (better quality filming), so you could look for that too.

I can't comment on the Eastwood stuff (I used Evercoat Fibertech for all of my heavy filling), but I'm sure they all work relatively similarly.

When I saw your post I thought about the leading edge of the driver’s door on my black-body gen 1 coupe that I had to build up ~5/8”. How much did you trim off of your nose? When I built my door up I roughed up the back-side of the outer skin, epoxied a piece of glass cloth to the back that stuck out toward the front of the car on that side about 1” (created a shelf to make the panel longer using HSRF), then spread HSRF on that shelf about the thickness of the outer door skin. Once the HSRF hardened I ground down the gelcoat on the outside of the door (and the HSRF) about the thickness of the glass cloth I used and about an inch back from the leading edge if the door. After it was all smoothed out and lower than the gelcoat, I epoxied a strip of glass cloth onto the outside of the door to keep the HSRF from breaking off of the leading edge of the door. Once the extension was all cured I trimmed the edge back to where it needed to be to get the gap I wanted. Before I started doing any material add to the front of the door I had the hinges adjusted and the rear and lower edges all finished and gapped the way I wanted them so I’d know all of the gap work would be on the leading edge with no further hinge adjustments needed. After it was all cured I used fiberglass jelly (yeah, I know, Bondo is a bad word around here but it’s readily available at Walmart cheap, is owned by 3M who also makes HSRF, and it works!) to build it back up close to the height of the body just ahead of the door, and finished filling it with Rage Gold. So I essentially built up the leading edge of my drivers door with HSRF sandwiched between glass cloth and epoxy to support it. Was it the way others would do it? No idea, but it worked for me. However much you need to add, you probably need to support it above and below the edge because, regardless of the material you use, if you only attach it to the edge, it will be very easy to snap off. I’m not very good at posting pictures but if you send me your e-mail address I can send pictures of my door fix.

Good luck!!!
